comment Tell if a process is under systemd, init.d or Upstart control
Because systemd has PID 1 (the topmost one), which is the only allowed top level process. This behavior of systemd is often criticised. So any process released from it's parent is parented by systemd. If you use Upstart or init.d scripts on a systemd-free system, you see that most processes are just below init, despite the fact most of them where launched by Upstart or init.d scripts. On your system sporting systemd, you will see any process released by its parent below systemd, so you cannot tell who has launched the process in the first place that way.

comment Tell if a process is under systemd, init.d or Upstart control
I don't think so. Looking at pstree at my system, most of the processes seem to have detached from their parent. There are only a few processes started by my desktop session, so most of the processes in the topmost level must have been started by some init deamon I guess.

Ow... I heard of --cached before, but thought it would remove files from the index. Thanks!

comment Is there an easy way to do a host lookup by MAC address on a LAN?
Consider: I make some devices. Others make some devices. They all met, another one connects a router. All leave. Some day someone replaces the router. I cannot configure the router, neither the other devices. The owner of the whole mess likes it if it just works. So at day one, when I bring my device, I have to configure it to just work as long as possible, interoperating with some other of the devices. That's all. If all machines would serve zeroconf with smooth names and the router would relay it between LAN / WLAN etc. all would be fine. Of course this never happend.

Yes, I like that way to find out the IP adress, but I cannot use the MAC address in some software expecing an internet address / URL / hostname. So my question is about how to map the MAC address to some local host address that any software can look up.

comment Is there an easy way to do a host lookup by MAC address on a LAN?
I add some machines or software to existing machines on an existing network. This machines need to use services of already existing machines in the same network. I do not have the rights to install zeroconf to the existing machines, but my machines or software need to use services of those machines reliably. The networks may be modified, routers replaced etc. so I cannot rely on some router's features, nor on zeroconf deamons on the foreign machines. So the only sure way to always identify these machines are their MAC adresses as those won't change this often...

Some LAN routers does in fact show such behaviour by default, and assign stable IP adresses as long there are enough left. However, I cannot rely on a feature some routers have. Some other routers expose linux hostnames in their DNS, which is a cool feature, but again this is not for granted. So when working with foreign networks, I need a reliable name assignment. Which may be done by avahi, if all devices are delivered by me. But foreign devices may not have avahi services running, so the only way to find those devices reliable would be the MAC address.

comment How to merge a git repository once split off without history
Related, yes. But it lacks the continous history I need, as there the two projects that get to be merged are unrelated, while in my case, the second one is a ancestor of some commit in the master repo.
