Package: jackd2
Version: 1.9.7~dfsg-1
Severity: normal
currently libjack "recommends" to install jackd, which usually evaluates to not
automatically install jackd if a package depends on libjack.
i read bug-report #442814 which implemented the change from "suggests" to
"recommends" but i am not totally convinced that i can follow the argument
(being myself rather audio-centric, so i have a natural bias ;-))
in short:
- a lot of audio-packages have jack support and thus depend on libjack
- installing libjack does not mean that jackd _must_ be installed (great, i like
weak dependencies)
- however, installing libjack will not trigger an installation of jackd (due to
the _very_ weak dependency), thus most installations will end up without jackd
installed (that was the purpose of #442814)
- if the user wants to use the jack-enabled application (which they installed
using apt), it will not work in most of these installations as jack cannot be
started, giving a cryptic error (e.g. "/usr/bin/jackd not found"), leaving the
use alone
i therefore suggest to raise dependency-level of libjack towards jackd to
"suggests" again, so people will actually be able to use their installed
jack-enabled applications.
alternative suggestions:
- the packagers could manually add "Suggests: jackd" to each package;
this is ugly as it has to be done for each and every jack-enabled package and
requires a lot more packaging ressources.
- add a new mechanism to apt, maintaining a "recommendation score" for each
package (A) which is raised whenever the user installs a package (B) that
'recommends: A'; once several packages recommending A are installed, A could
enter auto-install mode (a la 'suggests') thus people focusing around a
group of
applications (e.g. audio people) will get what they expect;
this is ugly, as people installing loads of similar software will probably
install the recommended application as well, whereas the occasional user
will be
left without e.g. jackd and a "non-working" system;

FWIW, I also agree with this. Installing a package which supports
libjack as one of many backends does not necessarily mean that you want
to install jackd as well.
Since this bug is 5 years old with most people saying that jack
shouldn't be changed, I'm going to close the bug now.
Thanks,
James
