No, the REGISTER means it only gets done when the /dev/sg0 device is |
| 24 |
registered in the devfs namespace. The only real difference between |
| 25 |
that line, and: |
| 26 |
|
| 27 |
REGISTER ^sg.*$ PERMISSIONS root.disk 660 |
| 28 |
|
| 29 |
is that above works for *all* /dev/sg* devices, and have group as "disk" |
| 30 |
and not "cdrw". devfsd knows to give the permissions to the real device |
| 31 |
in a line such as above. |
| 32 |
|
| 33 |
The real fix for modules, is the line: |
| 34 |
|
| 35 |
LOOKUP ^sg.*$ MODLOAD ACTION sg |
| 36 |
|
| 37 |
which cause the "sg" module to be loaded when you "lookup" (try to |
| 38 |
open) /dev/sg* |
