The previously bundled libraries are now individual ports, therefore manual
action is needed to upgrade.
IE: pkgrm samba; prt-get depinst samba
/etc/rc.d/samba will now start all samba daemons: smbd, nmbd and winbindd,
previously it didn't start winbindd. In most cases not all of them are
needed, so now there are also individual scripts to suit all needs.
