He's not asking what to type at that point, he's asking how to keep the kernel from stopping at that point and just do the (possibly destructive, but often-times all that gets damaged/moved to lost+found, is open logs that were open when the system went down) fsck.

(Unfortunately I do not know the answer as to how to tell the initial fsck just to go ahead and do the destructive fsck pass, without human intervention, as I wouldn't want it to do that, but I see where the communication misunderstanding is happening in the e-mail chain.)

He's saying the desktop machines are "throwaway" and he doesn't want to take the time to go over and look... do the fsck and if it trashes the filesystem, he'll just re-image the machine later.  Meanwhile, the user isn't confused by the fsck message or interrupted by it, if the machine finds filesystem problems at boot time.

I would assume this is often a desired behavior on machines that have poor AC power at remote sites.   Give the fsck a try if I'm not there.
