Upgrade from v5.0a to v5.1

Remount the disk read/write (remount w).
Make sure to rename or backup files that you have made
changes to (rc.local or similar) and is included in
this upgrade.

Copy the patch to /tmp and in the /tmp directory do:

tar Uzxpf /tmp/patch.50a-51.tar.gz

Adjust config files, restart daemons and remount the disk
read-only (remount r). Make sure to set the password and
check the /etc/hosts.allow file.
