Subject: [PATCH] man: using WantedBy=default.target is not a good idea

We had several users, that wrote their unit files with
WantedBy=default.target because it should be started "every time".
But for example in Fedora/CentOS/RHEL, this often breaks for
example selinux relabels (where we just want to do a relabel and reboot).
