The distro rules are the best example you can get and the use of
dev.d/ is no longer recommended.

From: Bill Nottingham <notting@redhat.com>
Changed reading of firmware blob to mmap and let firmware_helper
follow the setting of the log level with UDEV_LOG.

Rules can be precompiled and stored on disk for initramfs, to avoid
parsing the rules with every event again and again. Also the OWNER and
GROUP names are already resolved to numerical values in the compiled
rules. This flag is used for the upcoming move of the rules parsing
into udevd:
If the real root is mounted udevd is started and parses the rules
only once. The event processes will inherit the already parsed rules
from the daemon, so we want to ignore any precompiled rules and
use the real rules files and watch the filesystem for changes to
reload the rules automatically.

strlcpy counts the sourec string lengt and is therefore not suitable
to copy a defined length of characters from one string to another.

Copied from Kay's rules from the SuSE package.

This rule:
RUN+="socket:/org/kernel/udev/monitor"
send the event to the running monitor. Running udevstart give a nice
monitor output. Also the delay between the kernel uevent and the udev
udev event can be investigated:

RUN="socket:<name>" will send the environment in the kernel uevent
format to the named destination. Using the socket instead of the program
to pass the hotplug events to the HAL daemon, cuts down the running
time of udevstart from 0.8 to 0.4 seconds on my box.

Solaris uses volume_id now and they fiddled around with configure scripts
to map the linux kernel int types. Adding the types locally to volume_id
breaks the klibc build, so just switch to these ugly types and forget it. :)

This will allow us to have whole blocks of rules to skip
conditionally. The following section creates the node "yes":
GOTO="TEST"
NAME="no"
NAME="no2", LABEL="NO"
NAME="yes", LABEL="TEST"
NAME="no3"
|
|
This way we can run a rule if a certain key is not set by:
ENV{key}="" or ENV{key}!="?*"

Note, this assumes that you are putting your device nodes in /dev/, the
better thing to do is use the RUN= rule and not rely on this program at all.
