Upgrade from v5.12 to v5.13

Remount the disk read/write (remount w). Make sure to rename or backup
files that you have made changes to, for example /etc/passwd,
/etc/shadow and /etc/ntp.conf. Note that the original default password
will be set (hades12).

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

tar Uzxpf /tmp/patch.512-513.tar.gz

Adjust config files, restart daemons and remount the disk
read-only (remount r).
