I think I tried something like that to setup the ldattch for the PPS and 
systemd nuked the backgrounded ldattch job.

Is there a shell command to daemonize a command?  What are the right words 
for what I want to do?  I want to make a job invisible to systemd.

I'm thinking of something like:

The file name isn't critical.  That's where I put stuff in the pre-systemd 

These are my opinions.  I hate spam.
