I am doing lab for RHCSA, and trying to replace /etc/inittab from RHEL6 dvd.

I entered my rhel6 box in single user mode and mounted dvd, but I dont find inittab file? any hints?

# mount /dev/dvd /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
# find /mnt -name inittab
#

if it is read ONLY then it is READ ONLY and you can not edit it

you really do not want to boot into "single user" or rescue mode unless there is no other options
inittab will be in the ram until you reboot
as a normal user log in then raise to root and use the mv command

Code:

su -
cd /etc
mv inittab inittab.old

write the one you want with vi

Code:

vi /etc/inittab
