There's no quick answer, but there is an answer which doesn't involve
backing up to tape and remaking your partitions. The idea is to use hda7 for
/opt and then reuse hda6 for /. Steps would be
init 1 # so that as little as possible is running
find . -xdev | cpio -pmd /spare # copy /opt to its new location
mkdir OLDOPT # keep old /opt stuff for the moment, just to be sure . .
mv * OLDOPT # Ignore error message
mv OLDOPT/lost+found .
find . -xdev | cpio -pmd /opt # copy / to its new location
Now you'll need to edit /opt/etc/fstab because in the new world order, / is
on hda5 and /opt is on hda7 and /spare is temporarily gone. Booting is
another issue. LILO as shipped with RH6.1 won't boot from hda6. You can get
over that pro tem by using a boot floppy. Long term solutions would be
i) make a separate partition for /boot on hda1 - 20M should be loads, and then
you could use the rest of hda1 for /spare
ii) install the new version of LILO which can boot from beyond the 1024 cylinder
barrier, with appropriate hardware.
This whole thing illustrates the rightness of the one big root filesystem principal.
