Recommended sysadmin books or book lists?
I'm looking for resources that provide lists of and ratings for recommended Linux sysadmin books.
I am helping to get a friend of mine up to speed as a Linux sysadmin. He plans to admin a Fedora-Core-based web and email server running a variety of applications.
I am a long-time sysadmin for a variety of Unix systems, most recently Linux, and I run my own web and email server. I of course have some of my books I can reference to my friend, but many are several years old (some of them over 10 years old).
I am hoping that there may be some resources on the web that the community here can point me to that can provide a list of the most-popular and/or best-critiqued sysadmin-oriented books for a new Linux sysadmin.
I have my own specific, favorite references for applications like qmail, postfix, Apache, MySQL, etc. Further references for these are also welcome. For now, I'm looking for the "best" general Linux sysadmin books for now, possibly with a slant towards web-and-email server admin.
(I attempted some brief searches for things like "recommended books" in these forums, but did not turn up anything. Sorry if this is a faq.)
Thanks for any help,
