Subject: disable the cgroups release agent when shutting down
|
||||
|
||||
During shutdown, when we try to clean up all remaining processes, the
|
||||
kernel will fork new agents every time a cgroup runs empty. These
|
||||
new processes cause delays in the final SIGTERM, SIGKILL logic.
|
||||
|
||||
Apart from that, this should also avoid that the kernel-forked binaries
|
||||
cause unpredictably timed access to the filesystem which we might need to
|
||||
unmount.

Subject: cgroups-agent: remove ancient fallback code; turn connection error into warning
|
||||
|
||||
During re-execution and shutdown cgroups agents might not be able
|
||||
to connect to systemd's private D-Bus socket, the printed error to
|
||||
the console is misleding in that case, so turn it into a warning.
