According to the readme[1] of systemd, CONFIG_CFS_BANDWIDTH is required for CPUQuota= in resource control unit settings. So it should be checked when installing systemd.

Similarity, CONFIG_CGROUP_SCHED and CONFIG_FAIR_GROUP_SCHED are required for CPUShares= in resource control unit settings. Maybe they should be checked too.

I don't think it makes sense to check for every optional kernel feature that systemd could possibly use. Especially when not used by default.
