Salvage YDL3 install?

[yellowdog-newbie@lists.terrasoftsolutions.com]

I managed to bork my YDL3 install by accidentally deleting my /etc/fstab file 
while editing it.  On startup I get "Warning: couldn't open /etc/fstab: No 
such file or directory."  Reinstalling isn't an issue but would like the 
learning experience  if recreating the /etc/fstab file is possible either 
manually or via install rescue with CD.  My partitions are hda16 for ext3 and 
hda15 for swap.  Any guidance gratefully appreciated.  I'm not afraid to lose 
current install trying, there's nothing that can't be reinstalled.

Thanks!
