Reminds me of when I had an RTL crash and then couldn't log in after
rebooting. Starting up in single using mode and looking around some
revealed that the access flags of the crypto library and some other stuff
had changed! Scary, but easy to fix, and I never found any other broken
stuff on that system.
Anyway, the point is that *anything* can happen to a tradition file
system if you crash the kernel.
If you really *must* run RTL stuff directly on your workstation, switch
to some journaling file system, like reiserfs. Another solution would be
to have only a boot + swap drive in the RTL machine, and run the root fs
on a server via NFS or similar. Nothing is *totally* safe, though, short
of booting from a read only file system. (If it's on a local hard disk,
it would have to be one with hardware write protection. Some SCSI drives
have jumpers for that.)
