Restarting Amd
==============

   Before Amd can be started, it is vital to ensure that no other Amd
processes are managing any of the mount points, and that the previous
process(es) have terminated cleanly.  When a terminating signal is set
to Amd, the automounter does _not_ terminate right then.  Rather, it
starts by unmounting all of its managed mount mounts in the background,
and then terminates.  It usually takes a few seconds for this process
to happen, but it can take an arbitrarily longer time.  If two or more
Amd processes attempt to manage the same mount point, it usually will
result in a system lockup.

   The easiest and safest way to restart Amd, without having to find
its process ID by hand, sending it the `SIGTERM' signal, waiting for Amd
to die cleanly, and verifying so, is to use the `ctl-amd' script, as
with:

     ctl-amd restart

   The script will locate the process ID of Amd, kill it, and wait for
it to die cleanly before starting a new instance of the automounter.
`ctl-amd' will wait for a total of 30 seconds for Amd to die, and will
check once every 5 seconds if it had.
