There's physlock[0] as well, as vlock (apparently) has some limitations according to physlock(1):
physlock is an alternative to vlock, it is equivalent to `vlock -an'.
It is written because vlock blocks some linux kernel mechanisms like
hibernate and suspend and can therefore only be used with some limita‐
tions.
I can't attest to this as I've only used vlock, so correct me if I'm wrong.
