Re: User for startupitem.executable
The asterisk example wouldn't work here because it depends on the
executable supporting being run as a different user.
The -U option.
Thank you anyway Ken.
Although the mongo example using sudo launches an additional process, it
works because daemondo and in turn launchd monitors the whole thing, i.e.,
"sudo -u ${user} ${prefix}/bin/executable"
instead of monitoring
"su -c" only.
Where the call to "executable" gets lost. In other words, with su, launchd
and daemondo automatically restart the su process but not the "executable" .
So, I'll go with his approach.
Thank you Rainer.
In the future I will use macports-dev for Portfile writing related
discussion as noted in
https://lists.macosforge.org/mailman/listinfo/macports-dev
*Discussion for MacPorts development and Portfile writing. *

Just for the future, Portfile development is usually discussed on
macports-dev, where you would reach more developers. The discussion on
macports-users is about usage of the port command and problems with
installs and upgrades.

A few ports use this approach, citing from the mongodb port:
startupitem.executable sudo -u ${mongouser} ${prefix}/bin/mongod ...
While this adds an additional processes to the hierarchy, I do not see
any problem with that. The su/sudo keeps running until the command exits
and any signals sent to su/sudo will be relayed to the executed process.

Re: User for startupitem.executable
Here's a snippet from another port that might help:
startupitem.create yes
startupitem.netchange yes
if {[getuid] == 0} {
startupitem.executable ${prefix}/sbin/asterisk -d -U asterisk -G asterisk
} else {
startupitem.executable ${prefix}/sbin/asterisk -d
}
and there is a discussion in the mailing list about this from years gone by
the might be worth reading if that doesn't happen:
Hope this helps.
