Of course, it then doesn't escape $ in the offsets.
But, it looks like your script isn't up to date.
I'm fairly sure the current script should output:
 -fstype=cifs,username=USER,password=PASS \
         "/C" "://xp0/C" \
         "/ADMIN$" "://xp0/ADMIN$" \
         "/C$" "://xp0/C$"

which is why I thought we shouldn't need the "\" escapes.
Can you check your auto.smb against the one attached please, in
particular the last line at the bottom of the "/Disk/" block should be:

print " \\\n\t \"/" dir "\"", "\"://" key "/" loc "\""

Ian
