These links are overwritten by systemd installation:

smtp0:/sbin# ls -l *init* # Look
lrwxrwxrwx 1 root root    20 May 26 16:40 init -> /lib/systemd/systemd
-rwxr-xr-x 1 root root 35216 Jul 18  2013 init.sysv

lrwxrwxrwx 1 root root    10 Jun 13 07:26 telinit -> runit-init

which breaks the runit boot of the machine.
