On RHEL 6.2-based systems (like Scientific Linux 6.2):
# Set to ‘/sbin/sulogin’ to prompt for password on single-user mode
# Set to ‘/sbin/sushell’ otherwise
Then if you add an ‘s’ to the grub entry when the server boots it will ask you for a password , or hit ctrl-d. Ctrl-d makes the server enter normal boot (telinit *).
Should all linux machines be installed this way? To me this sounds like a definite deal, especially if you have the console physically or remotely accessible.

CentOS 5.8 was released today 8th of March.
You can download it from many mirrors, for example from FUNET:
It installs just fine on an HP DL360 G7 with P410 and P411 controller.
CentOS has as far as I understand been slower at releasing updates than Scientific Linux (for example 6.2 was out 5 days earlier on SLC than on CentOS), this was not the case today though, SLC 5.8 is not available yet. Why?
