In Ubuntu (which is my daily use distro), /var/lock happens to be
cleaned on boot by virtue of it being mounted as a tmpfs filesystem.
However, there is nothing in the FHS
(http://www.pathname.com/fhs/pub/fhs-2.3.html) that says /var/lock
must (or even should) be cleaned on reboot, whereas /tmp does have a
recomendation to do so.
I agree that a sample cleaning script would be nice to have, and would
get rid of any potential need for PID/datestamp checking.
