[systemd-devel] regarding to cgroup siblings mask

[WaLyong Cho]

Hi,

In recent systemd(from some month ago), when a unit has a mask for cpu
or blockio or memory, this mask is also propagated to siblings by
unit_get_target_mask().
According to some of comments, it seems intentional.

Could anyone explain why?

In our system, some of service have MemoryLimit= options. By this
options, all of other services also create its own cgroup in memory. In
mobile system(or some of other embedded system), this can be heavy load.

If this can be configurable, how about add a configuration for cgroup
mask propagation to siblings?

Thanks,
WaLyong
