libsane and acl group selection in udev rules

[Martin Owens]

As per the launchpad bug #773617[1] we've managed to track a
multi-release issue in oneiric to a packaging/acl issue.

It appears that the 40-libsane.rules file contains the following line:

ENV{libsane_matched}=="yes", RUN+="/bin/setfacl -m g:scanner:rw
$env{DEVNAME}"

Which should add the scanner to the scanner group and allow network
scanner sharing to work again. But we also have a saned group which I
believe the saned network scanner is using instead of scanner.

Should we change the setfacl to use saned? change saned to use the
scanner group? Add both scanner and saned permissions into the rules
file? Or add the saned user to the scanner group?

Please advise.

Best Regards, Martin Owens
