Hello, I'd made two different services. One has *CPUSchedulingPolicy=rr* and the others has *CPUShares=*.
# cat foo.service [Unit] Description=foo has CPUSchedulingPolicy= [Service] RemainAfterExit=yes ExecStart=/bin/true CPUSchedulingPolicy=rr # cat bar.service [Unit] Description=bar has CPUShares= [Service] RemainAfterExit=yes ExecStart=/usr/bin/hello.sh CPUShares=100 foo.service is activated well if bar.service is not activated. # systemctl start foo.service; systemctl status foo.service bar.service foo.service - foo has CPUSchedulingPolicy= Loaded: loaded (/usr/lib/systemd/system/foo.service; static) Active: active (exited) since Mon 2014-11-17 23:32:44 KST; 5s ago Process: 2702 ExecStart=/bin/true (code=exited, status=0/SUCCESS) Main PID: 2702 (code=exited, status=0/SUCCESS) bar.service - bar has CPUShares= Loaded: loaded (/usr/lib/systemd/system/bar.service; static) Active: inactive (dead) But if bar.service(what has CPUShares=) then foo.service failed on sched_setscheduler().
