* add command to systemctl to plot dependency graph as tree (see rhbz 795365)
+* make logind reserve tty10 or so for text logins, so that gdm never picks it up
+
+* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
+
+* isolate for getty is still broken, due to logind
+
+* don't umount /usr
+
+* default unix qlen is too small (10). bump sysctl? add sockopt?
+
* support units generated by a generator and placed in /run/systemd/system/; the directory is
currently ignored because it is empty before the generatores are executed
