You mean a sysctl to specify whether to require CAP_SYS_ADMIN for
restart(2)?

Yeah I wouldn't object to that - it certainly seems like something
sane for an admin to use depending on their users.

Though I think the bigger fish to fry first is whether we only support
whole-container checkpoint/restart.  If that is the case, then
CAP_SYS_ADMIN will always be needed for restart since it will always
unshare some namespaces.
