While that's true (you can lose data), most people when confronted with
the "should I correct this?" dialog during fsck simply hit "yes"
anyway. I've been using Linux since the early 90's and unix since the
mid-80's and still find the output of fsck to be somewhat cryptic.
If you want the machine to come up in an automated fashion (a headless
system) then I don't really see any other way of accomplishing this.
Personally, when I have a machine that's wedged or doesn't survive a
reboot, I consider that a cue to visit (or send someone else to visit)
the datacenter to find out why. Relying on some of the "technicians"
I've seen in various datacenters in NYC/LDN/SFO/HK to troubleshoot the
system just isn't an option. Troubleshooting generally means repeatedly
leaning on the power button until it either recovers by itself or
completely melts down. 8-)
