Controlling Hlfsd
-----------------

   Much the same way Amd is controlled by `ctl-amd', so does Hlfsd get
controlled by the `ctl-hlfsd' script:

ctl-hlfsd start
     Start a new Hlfsd.

ctl-hlfsd stop
     Stop a running Hlfsd.

ctl-hlfsd restart
     Stop a running Hlfsd, wait for 10 seconds, and then start a new
     one.  It is hoped that within 10 seconds, the previously running
     Hlfsd terminate properly; otherwise, starting a second one could
     cause system lockup.

   For example, on our systems, we start Hlfsd within `ctl-hlfsd' as
follows on Solaris 2 systems:

     hlfsd -a /var/alt_mail -x all -l /var/log/hlfsd /mail/home .mailspool

   The directory `/var/alt_mail' is a directory in the root partition
where alternate mail will be delivered into, when it cannot be delivered
into the user's home directory.

   Normal mail gets delivered into `/var/mail', but on our systems,
that is a symbolic link to `/mail/home'.  `/mail' is managed by Hlfsd,
which creates a dynamic symlink named `home', pointing to the
subdirectory `.mailspool' _within_ the accessing user's home directory.
This results in mail which normally should go to `/var/mail/`$USER'',
to go to ``$HOME'/.mailspool/`$USER''.

   Hlfsd does not create the `/var/mail' symlink.  This needs to be
created (manually) once on each host, by the system administrators, as
follows:

     mv /var/mail /var/alt_mail
     ln -s /mail/home /var/mail
