why refuse to checkpoint ?
if I'm root, and I want to checkpoint, and later restart, my sshd server (assuming we support listening sockets) - then why not ?
we can just let it be, and have the restart fail (if it isn't root that does the restart); perhaps add something like warn_checkpoint() (similar to deny, but only warns) ?
