I wouldn't do it on a running system. Better to boot from a live CD or
similar and do it from there.
A simple live CD is sufficient:
Debian netinst minimal CD in rescue mode is sufficient to do so.
Do not forget to update the /etc/fstab configuration file with respect
to the change; to clean up the /var (and let an empty one) in the `/'
(root) partition.
It is simpler to move the partition in single user mode. Just issue the
command (as root)
Indeed. I will think about it next time.
# shutdown now
(not 'shutdown -h now' or 'shutdown -r now'), wait the system go down and
enter the root password when asked. You will have just a root shell
running. An even more secure way (in case single user leaves some program
running) is to reboot and pass the argument
init=/bin/sh
to the kernel by editing the kernel command line in grub. You will start a
system with only a running shell as pid 1 and the root mounted read-only.
Then remount the root read-write:
# mount -o remount,rw /
and do the dirty work. When you finish, unmount all partition other than
the root, remount the root read only with
# mount -o remount,ro /
and reset the computer (shutdown will do nothing).
