[bug#30532] [PATCH] Shepherd: Terminate all services upon SIGTERM or SIGHUP

[ludo@gnu.org (Ludovic Courtès)]

Hi Carlo,

Good catch!

Yes, that’s perfect.

Right, I’m not sure what’s wrong with that.  I’ve committed the same
files under po/ as I did for Guix:

--8<---------------cut here---------------start------------->8---
$ git ls-files po/
po/Makevars
po/POTFILES.in
--8<---------------cut here---------------end--------------->8---

Excellent!

I have one request: since the three tests differ only in the signal
name, could you make it a single test file and have a loop like:

  for signal in SIGTERM SIGHUP SIGINT

TIA,
