interesting note on fsck and journalled filesystems

Crash recovery has been more of an issue at our shop than most, because we use 
Unix/Linux in factory equipment.  People are turning the power off all the 
time without doing a shutdown.  Journalling filesystems have been a big plus.  
It's such a hassle to try to get a non-computer type to punch in 
"fsck -y /dev/sd0a", or something like it.  I could never understand the 
current reason for requiring a user to type in an fsck command anyway (not 
just limited to Linux, Solaris does it, too).  I knew one graduate student 
when I was in school that would actually repair inodes and recover files, but
I've meet no one else since then that would know what to do.
