This whole thread highlights the downside to Linux: Configuration hell.
And before you say anything, ask the somewhat obvious question: Why should the Kernel care about Systemd?

$ mount
Code:...... tmpfs on /sys/fs/cgroup type tmpfs (ro,nosuid,nodev,noexec,mode=755) cgroup on /sys/fs/cgroup/systemd type cgroup (rw,nosuid,nodev,noexec,relatime,release_agent=/usr/lib/systemd/systemd-cgroups-agent,name=systemd) cgroup on /sys/fs/cgroup/cpu type cgroup (rw,nosuid,nodev,noexec,relatime,cpu) cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio) .....

also not systemd, nor anything that was not written specifically to check if a service is running properly can know if a service is running properly
i'd say more on this problem but i feel the audience would not care
bdw;
even SIGSEGV can be handled by the process that got it
and a process can rexec itself with only minor annoyances (setting up sig handlers again)
think about it

Regardless, he's already written about it, and I'm not going to argue about something I don't understand well.Last edited by Nobu; 26 April 2014, 11:07 AM.

Guest repliedOriginally posted by Nobu View Postsystemd will know it crashed because it keeps track using cgroups, before somebody asks. This is completely unrelated to the service, and no configuration or patching is required for this to work.
This effectively break userspace stuff like ulatencyd or custom scripts around jails used by hosting.

Or, if you were talking about separate services altogether, whether those services are stopped or not depends on whether you add the depending services to Wants or Requires in the dependent service, or the other which way...I'm dyslexic, okay?Last edited by Nobu; 25 April 2014, 07:47 PM.

dependency handling is in .service files (in systemd-s case)Last edited by gens; 25 April 2014, 10:10 AM.
