Hi all,

as announced before [1], recent changes to the jack and jack2{,-dbus}
packages (now in [extra] and [community] respectively) have made the
previously shipped configurations obsolete and decoupled the audio group
from acquiring realtime privileges by default when installing jack.

The package realtime-privileges [2] has been created to serve as the new
way of achieving this by the means of a dedicated 'realtime' group, to
which users, that need the settings, must be added.
It is now an optional dependency to jack and jack2{,-dbus} and can of
course also be dependend upon from other packages if needed.

In theory, this change shouldn't mean much of a difference to users,
that need realtime (just install realtime-priviliges and add your user
to the realtime group: `gpasswd -a <user> realtime`), while it doesn't
have any consequences for users that have no use for it to begin with.

Best,
David
