@rnhmjoj could you have a look on this one too? Thanks. It's pretty trivial.

I can confirm it builds and everything in /bin runs.
Qtel is properly wrapped but so are all other tools. Is this necessary? I think that only Qtel is a Qt application. In that case you should disable the hook and manually wrap Qtel. See for example arx-liberatis package if you don't know how.

Also I noticed is this error when running bin/svxlink

TclVoiceMail: *** ERROR: The spool directory (/nix/store/p0csgl15hlgamcwqw3cinqbjafhm4wnq-svxlink-19.09.1/var/spool/svxlink/voice_mail) is not writable by the current user or does not exist.

I'm not sure whether it can be ignored (because I haven't configured it) or the software needs some patching to change this path.

@rnhmjoj Thanks a lot for your review. I missed both things actually. Now I fixed it so it's only wrapping qtel and not the rest. The spool dir error can be ignored as that is taken from the default configuration file, so it's possible to configure it (and to configure the location of the config file) at runtime.
