Some additional info: 

If I say "mount /usr", I get the "line 0" message, and neither
"df" nor "mount" shows the file system mounted.  But 
"mount /dev/hda6 /usr" claims "/dev/hda6 already mounted..."
and I can see the files in /usr with ls.

Right after booting, df shows all the local file systems mounted,
except /usr, which is sometimes there, sometimes not.  

Original question: 

What on earth does this mean?  

I upgrades from RedHat 4.2 (as I recall) to 5.2.  
Afterwards, my system comes up with lots of things
broken.  Turns out /usr is not mounted.  
mount /usr gives:
"line 0 in /etc/fstab is bad"
This messages also shows up during a reboot.  

Many other filesystems in my /etc/fstab come up mounted. 
mount <anyMountPoint> gives the message, but 
mount /dev/hda6 /usr works.  All umount commands
work.   

Even more mysterious,  umount -a unmounts everything
but "/", and mount -a doesn't mount anything.  But the
system boots up with all of the many other filesystems in
my fstab.  

There are 5 entries right ahead of the /usr entry, which look like:
allegheny:(pid4551)   /net   ignore 0 0 0
I suspected them, since they precede the only failing filesystem
entry, so I tried commenting them out.  After my _second_
reboot after doing this,  I still get the line 0 is bad message,
but it came up with /usr mounted this time.  The more
experiments I try, the crazier and more inconsistent things
get.
