Hi:
I hope I'm not offtopic.  I ran into something similar with a single
partition containing /boot.
Vi left a large numbered inode and a non booting
disk.
Boot with the install disk, and get a terminal.
Mount the hard disk, and cd there.

touch dummy
cp file dummy
rm file
mv dummy file

Better practice is to write a script with file replaced with $1, and run
'script file'.

Thanks,
Wilson
