If you only care about making it hard for someone to casually undelete
something, and aren't after high security wiping, there's options like:

Remount without journalling, e.g. as ext2, then shred.

Delete the files, fill the drive to capacity from /dev/random
or /dev/zero, then delete the filler.

If /home is a partition, reformat it.  (Actually format, not just the
usual pretend format that is usually done on hard drives, these days.)

The second has the potential to hang your system, if it needs some drive
space while you're in the middle of doing it.

(This computer runs FC7, my others run FC4, FC5 & FC6, in case that's
 important to the thread.)
