OK, some silly semantics: There are two things you could be talking
about: the "mount point" (where the file system shows up in the
directory structure, e.g. /boot) and the "label", which is a name
stuck on a file system.  Red Hat likes to make the label of a
filesystem the same as its mount point, so the filesystem mounted at
/boot would be labeled "/boot", but it don't gotta be that way.

I'm gonna guess you want to do both, so it'd be like this:

Figure out what device is /hot2 (e.g. /dev/hdc3)

Become Root

edit /etc/fstab, find the line that looks something like:
  label=/hot2   /hot2   ext3  blahblah  some numbers
and change both instances of /hot2 to /hoth2

umount /hot2

mv /hot2 /hoth2

If it's ext2 or ext3, do:
  tune2fs -L /hoth2 /dev/hdc3  (or whatever device is /hot2)

mount /hoth2

and Bob's yer uncle.
