Severity: wishlist
I spent quite a while debugging problems with permissions to USB scanner
devices: they were being created within group "root" rather then
"scanner". It turned out that udev needs to be restarted to begin to be
aware of this group. udev logs before the restart looked like this:

It would be nice if libsane postinst strict displayed a friendly message
encouraging to run "/etc/init.d/udev restart". :)
