CUPS backend plugins

[David Woodhouse]

The bluez-utils package now has a CUPS backend for bluetooth printers.
How should it be shipped?

The other CUPS backend which is shipped separate from CUPS itself is the
one in samba-client. That one is just shipped in the samba-client RPM,
and CUPS has a trigger script which makes a symlink to it from
/usr/lib/cups/backend/ on installation of samba-client.

Is there a reason why the trigger is done that way round -- in the
_cups_ specfile rather than the samba one? Or why we can't ship the
extra CUPS backend in a separate 'bluez-utils-cups' RPM which puts it
directly into /usr/lib/cups/backend/ instead of making the symlink in a
trigger script? Or any of the other possibilities?
