For the sake of example, I've let the card-independant dummy one, so
a cut/paste of this unit will work.
Here's the contents of /etc/systemd/system/jackd.service

A better approach might be to configure Rivendell itself to start the
jackd(1) instance. See RDAdmin->ManageHosts->[hostname]->JACKSettings.
That way, your jackd(1) configuration gets saved in the Rivendell
database and hence will be included as part of the regular backup
process, plus you eliminate the need to tweak the ‘rivendell.service’
unit file each time Rivendell is updated. The primary drawback of this
approach is that you will need to restart the ‘rivendell’ systemd
service every time those command-line parameters change. (While this
is a bit of a bother during the initial system setup, it’s basically a
non-issue once you’ve settled on the jackd(1) parameters that you want
to use).
Cheers!
aha... today I will try that!
I didn't before because I'm not sure whether I could set the promiscuois
environment variable that way, maybe it will get it from
/etc/environment anyways... or maybe I can set it with an export command
followed by a semicolon and then, the jackd command... I have to
experiment... I used a Systmd Unit because, on the uncertainty/novelty
of the rivendell stuff to me, I tend to stick with what I'm familiar to...
Regards.
