- The files in this directory are read by udev(7) and used when events
- are performed by the kernel. The udev daemon watches this directory
- with inotify so that changes to these files are automatically picked
- up, for this reason they must be files and not symlinks to another
- location as in the case in Debian.
-
- Files should be named xx-descriptive-name.rules, the xx should be
- chosen first according to the following sequence points:
-
- 00 rules that it is critical to be run first, usually
- only WAIT_FOR_SYSFS
-
- 20 rules that change the name from the device from the default
- (cannot be overriden)
-
- 40 rules that set the permissions of device nodes
- (can be overriden by later rules)
-
- 60 rules that add symlinks to device nodes
- (adds to those set in earlier rules)
-
- 80 rules that run programs (but do not load modules)
-
- 90 rules that load modules
-
- 99 rules that it is critical to be run last
-
-
- This scheme has been chosen so that user-supplied rules are normally
- named 50-*.rules for the right thing to happen.
-
- Packages should chose the approriate sequence point and add 5 to it
- (e.g. 25-iftab.rules, 45-libsane.rules, etc.) unless there is a need
- for a particular order.
