Subject Re: guacd not starting on boot
Date Mon, 11 Mar 2019 03:04:45 GMT

      Ok, rebuilt with the correct --with-systemd-dir=/lib/systemd/system and
now I had more problems.  Launched out of init.d it ran as root, launced out
of systemd, the unit file it created has User=daemon so it runs as daemon.
Problem with that is only root has access to /var/run and to the encryption key
file so I changed it back to root despite that being less secure.

      Lastly it still failed because it tried to start before /misc was mounted
which is where the key file was so I modified the unit file line:

    to: misc.mount

     /misc is the file system where I have the encryption certs and keys.

     Now it starts properly after a reboot.  Downside, as with when it ran
out of /etc/init.d, it is running as root which from a security perspective
is undesirable.

     What guacd should have is an item that goes into guacd.conf for user and
group so it can start as root, write the pid file and read the necessary
cert and key files, and then switch to said user and group just like Apache
httpd and tomcat do.

     Then it could be both secure and functional.
