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). João Luis.
