Bug#767429: dh-systemd: Please improve timer unit handling

[Andreas Henriksson]

Package: dh-systemd
Version: 1.21
Severity: wishlist

Dear Maintainer,

I've looked at how to make a package where upstream installs systemd
service and timer units to not start the service during package postinst.

I could do this with override_dh_systemd_start: dh_systemd_start --no-start myunit.service
but that didn't really accomplish what I wanted and there where no
"dh_systemd_start --remaining" like other debhelpers offer.
(If I have to manually list each and every unit explicitly that will likely
lead to me missing to update it when a new one gets added upstream.)

I'm now wondering if it possible to always make the assumption that
if something ships a timer unit, then it never wants the matching service
unit started (other then by the timer) ?....

I've made a patch for that, please see attachment and excuse my lack of
perl knowledge.

(It would also be useful to me if similar would be possible for services
that has a socket unit, and I'd only like them to be socket activated.
c.f. uuid-runtime's uuidd.socket / uuidd.service which always gets started
on package upgrade.)


Regards,
Andreas Henriksson


PS. dh_systemd_start contains a comment talking about dh_installsystemd which I
assume is an old leftover which needs updating. Also the --no-also option seems
to be undocumented.

PPS. Thanks for the readable perl-code! Even someone with lack of proper
perl skills could understand it.
