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-)
