More seriously, with a rescue image you can resize any partition as

True. You can do funky things with your Free (AIFB) OS. Once I faced the
same problem described here. I had gone crazy and created separate /boot,
/home, /var and /tmp. After installing packages left, right and centre one
fine day, /usr fills up and / has no space.
I then picked up a partition and moved its contents elsewhere. In this case,
I can see there are several mounted on /media/*.
I then did this to format the new partition and copy the contents from /usr
to the new place:
# mkfs.ext3 /dev/hdaX
# mount /dev/hdaX /mnt/tmp
# find /usr -depth | cpio -apdmv /mnt/tmp
# umount /mnt/tmp
I then booted the sytem via a live/install CD and mounted the old root FS on
to /mnt/tmp and did these things:
This is just in case you screw things up, rename the old /usr
# mv /mnt/tmp/usr /mnt/tmp/usr-old
# mkdir /mnt/tmp/usr
Now I opened the rootfs's fstab and added an entry to mount the newly copied
/usr into place:
/dev/hdaX /usr ext3 defaults 0 0
After unmounting, I rebooted into the new system, ran a bunch of programs to
see everything was OK. then ran the final command to get free space bliss:
# rm -fr /usr-old
Now a days, I just have one monolithic "/" partition ranging a few 100 GBs.
But constrained resources did teach me lessons in partitoning, custom
kernels and good system administration.
HTH,
