Bug#538051: jackd: configuration fails with status 30

[Aaron M. Ucko]

Package: jackd
Version: 0.116.2+svn3592-1
Severity: grave
Justification: renders package unusable (uninstallable)

jackd.config runs in -e mode, but fails to account that db_input will
return status 30 rather than 0 for questions the user has already
seen; this applies even on the first installation of (or upgrade to)
0.116.2+svn3592-1 on systems on which (thanks to apt-utils)
preconfiguration is possible.

Please allow db_input to fail by protecting it with "|| true" or (if
you want to be really strict) "|| [ $? = 30 ]".

BTW, I also observe that you appear to be treating debconf as a
registry rather than a cache, and would advise setting the current
value of jackd/tweak_rt_limits based on the presence or absence of 
/etc/security/limits.d/audio.conf.

Thanks!
