Yeah, that article points out that systemd kills off processes started
From udev after a certain timeout...
With the following ltspfsd.service file:
[Unit]
Description=LTSP Filesystem Daemon
[Service]
Type=forking
ExecStart=/usr/bin/ltspfsd

It's a little more expensive to always run pgrep, but haven't found a
simpler way to ensure that ltspfsd is actually running.
Ideally, it would at least detect if systemd was running, and then
respond accordingly, but at least this gets it working...
Could also add an init script and call "service ltspfsd start" instead,
which might work regardless of init system... ?
