In Debian, since version 2:3.3.10-1, the procps package has the systemd integration bits enabled. This means that now the “ps” command can display which (user) unit has started a process or to which slice or scope it belongs.
For example with the following command:
ps -eo pid,user,command,unit,uunit,slice
Last weekend was a pretty busy weekend as we had our first joined Debian GNOME/systemd sprint. 10 people gathered at my employer office Inuits in Antwerp to work together on GNOME and systemd integration in Debian.
I worked mainly on GNOME packages, helping with transitions and packaging new bits for the GNOME 3.12 release. We also discussed a lot of things like the switch of the team repository from svn to git and the version of GNOME that we are planning to ship in Jessie.
I really think this was a very constructive sprint and such event should happen more often, we already planned to do this again near the release of 3.14.
