Description Nils Philippsen 2008-02-13 04:37:34 EST
Description of problem:
sane-backends will contain HAL policy which sets ACLs on scanner devices.
Currently udev contains rules which change ownership of SCSI scanner generic
devices to root.disk which seems superfluous to me.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Attach SCSI scanner to system, switch it on
2. 'echo "scsi add-single-device ...." > /proc/scsi/scsi
Actual results:
root@wombat:~> ls -l /dev/sg3
crw-rw----+ 1 root disk 21, 3 2008-02-13 10:25 /dev/sg3

Expected results:
root@wombat:~> ls -l /dev/sg3
crw-rw----+ 1 root root 21, 3 2008-02-13 10:25 /dev/sg3

Additional info:
The rules in question are:

40-redhat.rules:8:ACTION=="add", KERNEL=="sg[0-9]*", BUS=="scsi",
ATTRS{type}=="[36]", SYMLINK+="scanner scanner-%k", MODE="0660"

50-udev-default.rules:70:KERNEL=="sg[0-9]*",            GROUP="disk", MODE="0640"

Perhaps the rules should be structured so the latter one (in 
50-udev-default.rules) takes effect only for non-scanner devices.
