Upgrade To FC 7: Unable to mount /tmp

[Ben Mohilef]

We are trying to upgrade an old hunk'o'junk dual athlon box from FC5 to 
FC7 using a DVD. Unfortunately the installer claims that it can not mount 
/dev/hda15 as /tmp and aborts. /tmp mounts nomally on FC5 ( not nosuec 
or noexec) and I can't find any unusual attributes. It fscks cleanly as do all 
the other partitions.

There are a spectacular dearth of diagnostics here. The FC5 works 
flawlessly.   Has anyone else seen this problem? Am I overlooking the 
obvious somewhere? A clean install is just not practical on this box. 

Thanks.
