| | I had similar problems with udev rules when adding a 2nd NIC and
| | needed to override the assignments which switched the original eth0
| | to
| | eth1.
| |
| | For some reason, despite all the info that says the over-ride
| | filename
| | should be alphanumerically "smaller", it only works if the file is
| | alphanumerically "larger". Which kind of make sense to me since a
| | later rule should override an earlier one.
| |
| | So instead of 49-, try 51- instead :D
| 
| 
| Didn't work either. The MODE stuff works in either case, but the GROUP
| stuff does not. I've just decided to use puppet to manage it instead
| for now and might revisit it in the future

BTW: Can anyone try this to see if it is in fact a bug or not?

Create a file called

/etc/udev/rules.d/99-udev-override.rules

that contains

KERNEL=="tty[A-Z]*", GROUP="some_other_group_than_uucp", MODE="0660", OPTIONS="last_rule"

with mode of 0644 reboot and confirm that the group permissions change or not.  If you change the mode however you will see that the mode *does* change.
