The product page for the book at the publisher's site ('http://www.mhprofessional.com/product.php?isbn=0071765654#') has an "errata" link... but that is only for existing errata... In my experience some publishers have a means of submitting errata directly to the editors, some authors provide a link (or address), and some authorship efforts fix upon collaborative means (e.g. a Wiki or Google Doc for submitting items)... so (from my perspective) it seems hard to guess what to do after one has encountered an (unidentified) errata item.
PS: The "Contact Us" page leads to a list of departments and clicking the one which applies to errata ("Editorial Offices") results in a page listing a number of editorial offices; the one labeled "Education and Test Prep" ('http://www.mhprofessional.com/pages/mhp/content/contact_us/editorial_offices/contact_education_testprep.html') has a number of editor names which allow direct contact... but none of those names are the same as the one listed on the back of the title page of the book itself...
PPS: Even if the list is very late for helping with the 7th edition of the text sending it along seems to be the right thing to do as it's always possible for errors/mistakes to carry over and (insofar as the errata have been identified) it would be a shame for someone to duplicate the effort...

Keeping in mind the concerns previously mentioned the following is a list of typos encountered in a reading of the first part, i.e. RHSCA portion, of the text; please consider addressing the solicitation of a preference regarding how this list should best be provided as, in this case, a scan of my (hand-written) notes could have been posted along with the original message containing the concern... but any greater effort at precluding any realization of the errors could not conceivably have been more intended and (obviously) less dismiss-able after the fact.
Spelling/Typing
pXXXV: "...or file-in-the-blank questions..." -> "...or fill-in-the-blank questions..."
pLI: "Install the packages need..." -> "Install the packages needed..."
p11: "...such as a USB." -> "...such as a USB disk."
p24: "...versions of the Choose A Language And Keyboard Type screen described in Steps 9 and 10." -> "...versions of the "Choose A Language" & "Keyboard Type" screen described in Steps 10 & 11."
p118: "...testing the functionality standard..." -> "...functionality of standard..."
p164: "...the output to following command..." -> "...the output to the following..."
p177: "...the hostname (or FQDN) configuration..." -> "...the hostname (or fully-qualified domain name, FQDN) configuration..." (first use of 'FQDN' acronym)
p181: "...network address / network mask..." -> "...network address/network mask..." (w/o a space)
p189: "...database of hostnames/FQDN and..." -> "...database of hostnames/FQDNs and..."
CH3 Labs: "So the first four lab..." -> "So the first four labs..."
p304: "...all data that isn't going to..." -> "...all data that is going to..."
p313: "...on a different type of virtual machine such as KVM." -> "...such as VMware."
p318: "...'ifconfig', and 'route', and 'dhclient' commands, you can..." -> "...'ifconfig', 'route', and 'dhclient' commands, you can..."
p324: "You'll boot a system into runlevel 1..." -> "...into runlevel 3..." (per the instructions that follow)
p357: '| grep formats' -> Same output for both commands (omit 'grep'?)
p362: "...you should be able to set up partitions set up to match..." -> "...able to set up partitions to match..."
p428: "To that end, you to understand..." -> "To that end, you need to understand..."
p433: "A connection to such (enabled=0)..." -> "...to such repositories..." OR "...as such..."
p448: "Subscription the RHN..." -> "Subscription to the RHN..."
p474: "For example, if to create..." -> "For example, to create..."
p485: "As long as the 'su' and 'sudo' command allows, users..." -> "...command allows it, users..."
p491: "...with an .sh is..." -> "...with a '.sh' is..." OR "...with an "sh" is..." (since the file extension concept is domain/language specific it should, formally, be indicated with apostrophes/quotes or typeface)
p494: "...(AD) services..." -> "...(AD) servers..." OR "...(AD) service-implementation hosts..."
p495: "Of course, if secure communication is being used to LDAP..." -> "...being used for LDAP..." OR "...to communicate with an LDAP server..."
p512: "...permissions on /home/infousers directory..." -> "...permissions on the /home/infousers directory..."
p517: "...in another room or another continent." -> "...in another room or on another continent."
p518: The second line beginning "#VNCSERVERARGS" is commented out (but shouldn't be)
p534: "...the script is run until just about any other jobs...is scheduled for execution." -> "...the script is not run until just about any other job... is scheduled for execution."
p536: "...the following command is functionally equivalent to the '/etc/init.d/vsftpd restart' command:" -> '/etc/init.d/vsftpd/stop'
Technical:
p18: "...you might go as low as 8GB for a hard disk..." -> A warning regarding later instructions suggesting FTP server & KVM installations might help as >8GB of hard disk drive space is required in the case of the same (especially when following along with the labs and copying the installation source to disk)
p34: "...labeled as a logical volume... then be initialized as a physical volume..." -> "...as a logical partition... with volumes..."
p38: "...at least the minimums shown in Table 1.1." -> A suggestion along the lines of that found on p16 (regarding an 80GB space) OR that found on p128 (regarding an 60GB space) might be appropriate as later commands, like those found on p81, provide directions for creating a separate '/var/lib/libvirt/images' space & at least one chapter exercise deals with LVM space and creation; even a different sample figure (i.e. Figure 1-11) might help readers who follow allow with the examples sequentially to properly plan and allocate space for following along...
p74: "...by a DHCP client." -> "...by a DHCP server."
p106: The installer gives a warning about an empty device; the warning has to be suppressed or anticipated...
CH3 Lab 3: script file is in error (manual 'down' & 'restart' results in working config)
p234: Step 3 ('iptables restart') results in "permission denied" (Use '/sbin/service iptables restart' instead? The '/sbin/service' prefix could also be added to the $PATH...)
p238: 'semanage' requires policycoreutils-python-* (not installed by default or as a result of the initially suggested configuration and examples/exercises)
p238: 'semanage -d michael' -> 'semanage login -d michael'
p244: 'sealeart' requires installation (should also be 'sealert')
CH4 Lab 5: Single arrow re-direction worked as would be assumed
p271: "...and press 'B' to boot this kernel." ('ENTER' seems required to boot the kernel from the edit screen)
p279: "...from Exercise 5-1..." (The referenced exercise doesn't contain the desired output; p278 could be referenced instead)
p299: 'system-config-services' not installed by default or as a result of the initially suggested configuration and examples/exercises
p314: "6. ... Click View | Details." -> "6. ... Click Edit | Virtual Machine Details, then "View | Details."
CH5 Lab 5: Lab 5 should be prefaced w/instructions to move '/root/backup' if existant as script cannot be run twice and directory exists when following along step-by-step w/the published version
CH5 Lab 7: 'chmod +x Ch5Lab?' ('?' should be '*' since "Ch5Lab7testfile" is correctly copied)
p356: 'tune2fs ^O has_journal' -> 'tune2fs -O ^has_journal'
p358: (7) Results in a message suggesting 'fsck' (with the command abending); running 'fsck' and then the command (both times it was tried) changes its type to 'ext4' even if 'fsck' is directed not to fix errors (output is same as 'grep format' from (2), i.e. program version only)
p367: "Based on the example in the previous section..." (No filesystems are necessarily mounted/created as p363 indicates mounting of the instantiated volume occurs later in the chapter)
p368: "Resize the formatted volume..." (No volume is formatted after logical volume is extended)
CH7 Lab 2: The script appears to only touch both files in question; re-installation of 'vsftpd' could/should be considered a legitimate solution for the exercise, as such...
p492: Exercise 8-4 doesn't seem to work when following linearly ('/etc/profile' might override the intended effect and/or instructions should read '~/.bashrc' instead)
CH8 Lab 2: Exercise might not be consistent due to ambiguity in the instructions (i.e. "to limit root logins to the sixth virtual console" can be taken two ways)
p519: Example did not work with a regular user account ("XAUTH: (STDIN:1) BAD DISPLAY NAME" message) but initially reports success ('geometry' option was enabled before the attempt)
p545: System configuration suggested by the first two chapters does not allow a regular user to create yearly cron jobs.
Formatting:
p102: First listed command is not centered/indented as the other commands on the page are...
p267: "BIOS/UEFI" should break after the slash (if at all)
p354/355: mkfs.msdos list item is repeated (with the second item being accompanied by a more verbose explanation/a parenthetical)
p522: Issue with the typeface of "Host" (not in bold)
p558: "Lab Questions" section might be redundant (in other chapters as well...?)
Suggested:
p17: "And as such access may not be slowed by network traffic, virtual CD/DVD drives may be as fast as network access from a host system." -> "As such, ... traffic; virtual..." (the context is clearly casual, and professional, but, generally, sentences shouldn't generally begin with "and" and "but"...)
p21: "From those media there's no fuss about a separate boot disk, no worry about network connections." -> "...boot disk and no worry..." OR "...boot disk & no worry..."
p34: "Basic Information On Logical Volumes" -> "Basic Information On LVM Logical Volumes"
p100: Ordering of information beginning with "...when I installed RHEL 6 on a KVM-based VM." should be reconsidered: The only directions regarding KVM before p100 are on p83 ("Configure a Virtual Machine on KVM") but do not include specific network installation source instructions; resultantly, step 4 on p106 cannot be followed & the idea of reading and following the examples sequentially is slightly less clear (e.g. Ch.2 Lab 1 first or Chapter 2 KVM install first? Lab 4 same as exercise 2-3?)
p121: "Strangely enough..." -> "Strangely, or perhaps not so strangely, ..." (this item, in context, comes after a mention of the security vulnerability of plain-text transmission, suggesting the intent is the opposite of what was written... though it does seem best to let the reader decide regarding the same)
p175: "...it's sent to the computer with that gateway." -> "...that gateway address." OR "...that gateway interface."
p185: "Now you'll work with the new default network management tool for RHEL6, the Network Connections tool." (consider omitting)
CH3 Labs: "...only KVM is a virtualization technology found on RHEL 6."- > "...on RHEL 6 by default."
CH3 Lab 4: "...in Chapter 1." -> "...in Chapter 1 and summarized on p188."
CH3 Lab 6: Backup file in '/root/backup' (rather than '/root')
p214: "...can read..." -> "...can only read..."
p295-296: Explicit mention of S* being start scripts and K* being kill scripts might be helpful if the example which later follows (on p298-299) is not sufficient for suggesting the concept...
p305: "The Address Resolution Protocol associates..." -> "Address Resolution Protocol associates..."
p307: "There is no requirement for the other directives shown in Table 5-7, including an NIS domain, for IPV6 networking, and a gateway address." -> "...shown in Table 5-7 (which includes directives for ...)
p310: Step 3 can be safely omitted
p369: "...I've deleted those partitions." -> "...deleted the previously configured partitions..."
p391: No explanation of '+auto.master'
p427: "For example, I use one to..." -> "For example, I have used one to..."
Grammatical:
pXXXVI: "...to test candidate qualifications as..." -> "...to test a given candidate's qualifications..."

p4: "As this is RHEL, this is based..." -> "As this is RHEL, the objective is based..."
p6: "...they are consistent with the outline of those courses." -> "...it is consistent with the outline of those courses."
p6: "This book covers the objectives associated with each of these exams." -> "...each of the exams." OR "...each of those exams."

p24: "...part way through..." -> "...part-way through..."
p24: "The first steps of the network installation starts in text mode..." -> "...steps... start..." OR "...step... starts..."
p47: "...of the actual RHEL 6; the steps..." -> "...of the actual RHEL 6 distribution...." OR "...the official RHEL 6 release..."
p47: "If you can't accept this agreement..." -> "If you can't accept the agreement..."
p58: "It's often used on other systems such as the Domain Name Service (DNS) server..." -> "...such as a..."
p70: "...but also it's... -> "...but it's also...
p87: "...there is no need to add any virtualization packages..." -> "...any of the virtualization packages..." OR "...any virtualization package."
p96: "...before starting that cloned machine..." -> "...before starting the cloned machine..." OR "...starting a given cloned machine..."
p103: "...as the virt-install command does not recognize that virtual hard device file." -> "...recognize virtual hard drive device files."
p105: "...the following is just excerpts..." -> "...the following are just..."
p110: "...whether they've been created to a Linux filesystem..." -> "...whether they've been initialized with a Linux filesystem..."
p111: "...a series of Kickstart file..." -> "...a series of Kickstart files..."
p128: "...on this system..." -> "...on your system..." (see the suggested item pertaining to p100)
p151: "...based on the Berkeley Internet Name Domain (BIND)." -> "...(BIND) standard."p168: "...there is no practical way to pass either any Red Hat exam unless..." -> "...to pass any..."
p172: "...a Domain Name Service (DNS), Berkeley Internet Name Domain (BIND), or nameserver." -> "...a Domain Name Service (DNS) server, Berkeley Internet Name Domain (BIND) server, or nameserver."

p179: "Of course, if networking were not configured during the installation process, there's..." -> "...networking was not..." OR "...networking services were not..."
p185: "With the number of users on multiple network connections, the Network Manager is designed to make that switching between say a wireless and an Ethernet connection as seamless as possible." -> "Given the number of users on multiple network connections, the Network Manager is designed to make switching between, say, a wireless and an Ethernet connection, as seamless as possible."
p185: "...all you need to know is how to configure a network card with that tool." -> "...a network card with the tool."
p202: "Standard permissions for Linux files are defined for users, groups, and others, which leads to the ugo" -> "...which leads to the "ugo" acronym."
p202: "Those permissions are read, write, and execute, which defines the rwx." -> "...which defines the "rwx" acronym."

PS: This message can be edited per your request (e.g. in the event there is a preference to have errata posted only in one place)...
PPS: Thank you for writing an awesome text! Taking an RHEL 6 RHCE test might be difficult given exam voucher purchase is subject to Red Hat's discretion... but maybe we can ask them to recommend the seventh edition of the text instead...
