I follow the OpenRC wiki example trying to set a cgroup to restrict service cpu usage, turns out it doesn't work at all Reproducible: Always Steps to Reproduce: 1. follow example at https://wiki.gentoo.org/wiki/OpenRC/CGroups 2. put the example line rc_cgroup_cpu="cpu.shares 512" at /etc/conf.d/boinc 3. /etc/init.d/boinc start Actual Results: /lib64/rc/sh/rc-cgroup.sh: line 64: printf: write error: Invalid argument Expected Results: boinc correct start with specific cpu shares val log from /etc/init.d/boinc start --debug as you can see there is a leading space in $val ++ echo / + local controller=cpu h=/ + cgroup=/sys/fs/cgroup/cpu/openrc_boinc + '[' -d /sys/fs/cgroup/cpu/openrc_boinc ']' + set -- cpu.shares 16 + local name val + '[' -n cpu.shares -a cpu '!=' cpuacct ']' + case "$1" in + '[' -n '' -a -f /sys/fs/cgroup/cpu/openrc_boinc/ -a -n '' ']' + name=cpu.shares + val= + shift + '[' -n 16 -a cpu '!=' cpuacct ']' + case "$1" in + val=' 16' + shift + '[' -n '' -a cpu '!=' cpuacct ']' + '[' -n cpu.shares -a -f /sys/fs/cgroup/cpu/openrc_boinc/cpu.shares -a -n ' 16' ']' + veinfo 'boinc: Setting /sys/fs/cgroup/cpu/openrc_boinc/cpu.shares to 16' + printf %s ' 16' /lib64/rc/sh/rc-cgroup.sh: line 64: printf: write error: Invalid argument + '[' -f /sys/fs/cgroup/cpu/openrc_boinc/tasks ']' + veinfo 'boinc: adding to /sys/fs/cgroup/cpu/openrc_boinc/tasks' + printf %d 0 + return 0 + local cpuacct= + '[' -n '' ']' + local cpuset= + '[' -n '' ']' + local devices= + '[' -n '' ']' + local memory= + '[' -n '' ']' + local net_prio= + '[' -n '' ']' + return 0
This is fixed in commit b20a195. This will be part of OpenRC-0.18. Thanks for the report and the debug log.
