My manager reminds me that "in the old Sun days", the ssh server came up first, *before* the fsck on boot, so that if there was a problem, and fsck was waiting for an answer, you could remotely ssh in, kill it, restart it, and answer (or give it the right flags).
Does anyone know if it's possible to have that happen with CentOS? It would be nice to have it boot that way, so that if you checked, and figured it should have been up already, you could handle the problem without coming in....
markI think having a decent remote console is the solution to that. DRAC, KVMoIP, Serial console, etc... I'm not sure how it could be considered safe to start services like sshd before the filesystem has been checked.
sshd can't come up before the fsck ... fsck is done on unmounted file systems. On the old Sun machines (and the new ones for that matter) there was a remote console (exactly what Brian mentions) that you had access to where you started the OS. This Console allow you to see things before sshd was turned on via the machine, but it was also on a separate IP address from the machine.
