On FreeBSD it will mostly work, but /proc can be turned off, and that is
commonly done on servers to reduce the attack surface. (/proc exposes stuff
for debugging like addresses that afaik can be used to attack).

Also on embedded and startup kernels it is sometims turned off.


Parsing "ps" is the best option I think.

FreeBSD too.
