There was an update of GNOME3 for FreeBSD 11 CURRENT, and now it is 3.14.2 instead of 3.14.0. The package that can really make a difference after this update is dbus – if left in rc.conf the way it ran in GNOME2 days, similar to this:
it will freeze the boot, and your console will be spammed with the race conditioned messages from dbus, so much that you will think that FreeBSD just switched to systemd, too 🙂
Simply abandon the old ways, and let a single “gnome_enable=YES” in the /etc/rc.conf take care about all of the dependencies it requires.
GNOME 3.14.0 did ignore it well, GNOME 3.14.2 does not forgive it in the rc.conf.
