For some odd reason, fsck has suddenly become confused about what 
"auto" means after I changed the root to ext3 and everything in fstab 
to auto. This is happening on a Redhat Pentium III box running 2.4.9 
and I also installed just recently util-linux 2.11l and glibc 2.2.4. 
fsck is 1.2.5 as indicated below.
fsck 1.25 (20-Sep-2001)
