I've emptied /tmp and /var/log and been through my old /home dir. "df"
still reports disk 100% full! Does mv and rm actually free up space?
I've done that one several MB of stuff, but it hasn't changed the
result of df...

I just had another look at df and thought I'd show you the odd result:

                  1k Blocks     Used         Available    Use      Mounted on
/dev/hda8    7439683        7196888    0               100%     /

Odd - right? There should be nearly 300MB free! (if I've read it right)

Ideas?   - Duncan
