We never used any of the libsysfs convenience features. Here we replace
it completely with 300 lines of code, which are much simpler and a bit
faster cause udev(d) does not open any syfs file for a simple event which
does not need any parent device information.

Simple %e enumerations never worked reliably outside of udevstart and
udevstart is no longer recommended to use.

All udev state is kept in /$udev_root/.udev/ now. No option to
configure that anymore, it will always be there.

The troff man pages will still be checked into the tree but the
source is DocBook XML format living in the docs/ directory now.
Start with the easy ones, the main udev page is still left to
rewrite.

Here's a long overdue update to the udev rules docs, based on lots of user
feedback from the last few months.
Mostly updates to keep up with the new udev features, some clarifications and
wording improvements. I added a section on rules for palm pilots due to the
excessive amount of mail I get about them. I removed the nvidia stuff because
it's out of date. Added another section about debugging using logs and
udevtest. Removed the thanks list because I haven't been updating it and there
are too many people to name now, sorry..!
This makes the udev operation completely lockless by storing a
file for every node in /dev/.udevdb/* This solved the problem
with deadlocking concurrent udev processes waiting for each other
to release the file lock under heavy load.
Here's an update to the documentation. It makes a few minor corrections and
adds info about multiple-symlinks.
It also seems that the patch I sent on April 27th (patching v0.53 to 0.54) was
not applied, so this patch includes that update too, which was also just some
small corrections plus added info on renaming network devices.
Here's an update for the writing udev rules document.
- Minor corrections/clarifications
- Added info about using NAME{all_partitions}
- Added more info about udevinfo, simplifying the rule-writing process
You can ignore the diff I sent you yesterday - according to the 20040415 bk
snapshot on codemonkey.org, you haven't applied it yet. This patch
incorporates that update, and some other changes I just made.
