2010-01-26 Matt Burgess <matthew@linuxfromscratch.org>
* 55-lfs.rules: Remove lots of rules that have been merged upstream.
* 61-cdrom.rules: Remove as upstream has a replacement.
* doc/*: Cleanup and rewrite now that the rules are much simpler.
2009-09-25 Bryan Kadzban <bryan@linuxfromscratch.org>
* 55-lfs.rules: Make the RTC rule (which runs setclock) work for people
that don't use the RTC-class driver -- add another copy of the rule,
using KERNEL=="rtc" instead of SUBSYSTEM=="rtc". Also move the ACTION
match before the assignment to MODE.
2009-05-23 Bruce Dubbs <bdubbs@linuxfromscratch.org>
* 55-lfs.rules: Set the rtc by udev upon boot. Removed aio device from
udev configuration so defaults are used.
2009-05-16 Bryan Kadzban <bryan@linuxfromscratch.org>
* 55-lfs.rules: Adopt udev permissions for random, urandom, kmsg, and
input devices (including psaux, which probably doesn't exist anymore
anyway).
2009-05-16 Matt Burgess <matthew@linuxfromscratch.org>
* 55-lfs.rules: Remove the block rule as it was only setting
permissions that Udev will set by default
* 55-lfs.rules: Remove the rfcomm rule as the group it sets is already
included in upstream's rule
* 55-lfs-rules: Remove the tape rules as the group they sets is already
included in upstream's rules
2009-03-15 Bryan Kadzban <bryan@linuxfromscratch.org>
* 55-lfs.rules: Remove the ISDN-handling rules (replaced with upstream's
version, which has a better match via SUBSYSTEM).
* 55-lfs.rules: Replace "uucp" with "dialout" now that udev has decided
to standardize on a Debian-like setup (uucp is for UUCP daemons to use
for privilege separation; dialout is for users and devices).
2008-12-07 Bruce Dubbs <bdubbs@linuxfromscratch.org>
* 55-lfs.rules: Change one line to use continuation so it does
not overflow the book's width.
2008-12-07 Bryan Kadzban <bryan@linuxfromscratch.org>
* 55-lfs.rules: Remove several rules that are either provided by upstream,
or that don't have any effect (there is no /dev/js or /dev/djs according
to devices.txt).
* 55-lfs.rules, 61-cdrom.rules: Replace ACTION=="add" with "add|change"
everywhere, per upstream's general request.
2008-11-11 Bryan Kadzban <bryan@linuxfromscratch.org>
* 55-lfs.rules, 61-cdrom.rules: Fix comments to use the right rule
numbers. Thanks to Trent Shea for the fix. Closes #2278.
2008-10-15 DJ Lucas <dj@linuxfromscratch.org>
* 55-lfs.rules: Override default perms on floppy disk devices provided
by 50-udev-default.rules. Thanks to Bruce Dubbs for the fix. Closes
LFS ticket #2076.
2008-05-21 Bryan Kadzban <bryan@linuxfromscratch.org>
* 81-firmware.rules, doc/81-firmware.txt: Remove. This rule is
already handled by udev's 50-udev-default.rules file. The docs
can be added back later if needed.
* Makefile: Don't install the above deleted files.
* 55-lfs.rules: Remove the device-mapper rule, since the upstream
50-udev-default.rules file handles it properly.
2008-04-02 Bryan Kadzban <bryan@linuxfromscratch.org>
* Makefile: Make the package DESTDIR-friendly by installing the docs
into a fixed $(PREFIX)/share/doc/udev-config directory, instead of
trying to figure out what version of udev was just installed.
2007-10-30 Bryan Kadzban <bryan@linuxfromscratch.org>
* 55-lfs.rules: Since the dialout group was renamed to uucp, delete
the rules that override upstream's assignment of the dialout group.
Replace "dialout" with "uucp" on the remaining rules.
2007-10-29 Bryan Kadzban <bryan@linuxfromscratch.org>
* 51-lfs.rules: Move to 55-lfs.rules.
* doc/51-lfs.rules: Move to doc/55-lfs.rules.
2007-10-27 Bryan Kadzban <bryan@linuxfromscratch.org>
* 25-lfs.rules: Some rules in here are duplicates of rules from udev's
new 50-udev-defaults.rules file; remove them. Override permissions
where needed elsewhere (and document overrides in comments).
* 26-modprobe.rules: Provided by udev's 80-drivers.rules and built-in
modaliases for SCSI device-type modules in 2.6.22+ kernels; remove.
* 25-lfs.rules: Move to 51-lfs.rules.
* 27-firmware.rules: Move to 81-firmware.rules.
* 81-cdrom.rules: Move to 61-cdrom.rules.
* doc/25-lfs.txt: Rename to 51-lfs.txt.
* doc/26-modprobe.txt: Rename to 80-drivers.txt, and modify to reflect
the upstream rules.
* doc/27-firmware.txt: Rename to 81-firmware.txt.
* doc/81-cdrom.txt: Rename to 61-cdrom.txt.
* Makefile: Use new filenames.
2007-07-31 Dan Nicholson <dnicholson@linuxfromscratch.org>
* 25-lfs.rules: Changed the usb_device rule tto create /dev/bus/usb
nodes if the usb_device in 2.6.22+ kernels. The rule was also changed
to only trigger on "add" events. This change is not backwards
compatible with older kernels.
2007-06-12 Dan Nicholson <dnicholson@linuxfromscratch.org>
* 25-lfs.rules: Fix the CPUID nodes from cpu/%n/cpu to cpu/%n/cpuid,
which is what's expected in userspace apps such as x86info.
2007-06-08 Bryan Kadzban <bryan@linuxfromscratch.org>
* 25-lfs.rules: Add rules for DVB devices (create nodes in /dev/dvb/)
and floppies (create extra nodes based on CMOS type), copied from
the SuSE rules file. Thanks to Alexander Patrakov for the bugreport.
2007-03-04 Matthew Burgess <matthew@linuxfromscratch.org>
* Makefile: Use `udevd --version' to work out what version of Udev is
installed (requires Udev >= 106)
2007-01-02 Bryan Kadzban <bryan@linuxfromscratch.org>
* 25-lfs.rules: Change CPU devices (cpu, msr, microcode) to be in
/dev/cpu/ and /dev/cpu/N/, to match Documentation/devices.txt.
2006-10-21 Bryan Kadzban <bryan@linuxfromscratch.org>
* Makefile: Add a missing backslash in install-extra-doc.
* 05-udev-early.rules, 60-persistent-input.rules,
60-persistent-storage.rules, 95-udev-late.rules: Remove. The book
will install these files from udev's etc/udev/rules.d directory
instead.
* Makefile: Don't install these rules files after all. Also, only
install corresponding docs if requested.
2006-10-20 Bryan Kadzban <bryan@linuxfromscratch.org>
* Makefile: Added; contains targets to install rules and doc files.
From Dan Nicholson.
2006-10-14 Bryan Kadzban <bryan@linuxfromscratch.org>
* 05-udev-early.rules, 60-persistent-storage.rules: Sync up with
upstream sample rules files (from udev-102), except for one rule
which is more specific in our tarball and should probably be changed
upstream.
* doc/60-persistent-storage.txt: Modify to match the changes. Also
fix a couple typos.
* 25-lfs.rules: Remove duplicate rules (ttyS[0-9]* is also matched by
tty[BC...S...][0-9]*, and ttyUSB[0-9]* is in there twice).
* 25-lfs.rules: Fix Alsa device KERNEL rules. Udev uses shell-style
glob matching, not regular expressions, so the old rules would match
nonsense device names like hw0asdf and pcmDzxcv. As long as the first
character after the "fixed" portion was in the list, the rule would
match; it wouldn't apply the same character range to later characters.
* doc/25-lfs.txt: Add a note on interaction between permissions and
symlinks.
2006-10-09 Bryan Kadzban <bryan@linuxfromscrtach.org>
* 25-lfs.rules: Fix fb[0-9]* device permissions (should use the default
0660).
* doc/25-lfs.txt: Fix typo: /dev/ptmx is given mode 0666, not 0660.
Also tweak the comment about other TTY devices.
2006-10-04 Bryan Kadzban <bryan@linuxfromscratch.org>
* 05-udev-early.rules: Remove WAIT_FOR_SYSFS="bus" rule. With kernel
2.6.18, this rule is no longer required.
* doc/05-udev-early.txt: Update to match.
2006-09-28 Bryan Kadzban <bryan@linuxfromscratch.org>
* doc/60-persistent-storage.txt: Explain persistent storage rules, or
at least the parts I understand. (I don't use DASD or netblock or
several other supported configurations.)
* doc/81-cdrom.txt: Explain 81-cdrom.rules.
* doc/95-udev-late.txt: Explain 95-udev-late.rules. Documentation is
now finished.
2006-09-26 Bryan Kadzban <bryan@linuxfromscratch.org>
* doc/60-persistent-input.txt: Explain (in probably too much detail)
60-persistent-input.rules.
2006-09-24 Bryan Kadzban <bryan@linuxfromscratch.org>
* doc/05-udev-early.txt: Rewrap to fit 80 columns.
* doc/26-modprobe.txt: Explain 26-modprobe.rules, and modaliases.
* doc/27-firmware.txt: Explain 27-firmware.rules.
2006-09-24 Bryan Kadzban <bryan@linuxfromscratch.org>
* doc/25-lfs.txt: Explain 25-lfs.rules.
* 25-lfs.rules: Use SYMLINK+= for isdn/capi20 also.
2006-09-23 Bryan Kadzban <bryan@linuxfromscratch.org>
* doc: New subdirectory to contain documentation of rules
* doc/README: New file, top-level documentation
* doc/*.txt: New documentation files, one for each rules file. Only
05-udev-early.txt has anything in it.
2006-09-23 Bryan Kadzban <bryan@linuxfromscratch.org>
* 25-lfs.rules: Add "ignore_device" to OPTIONS for DRI devices, instead
of setting NAME to an empty string. This matches the way we ignore
devmapper / LVM devices.
2006-09-22 Bryan Kadzban <bryan@linuxfromscratch.org>
* 60-persistent-input.rules, 95-udev-late.rules: Import from udev-100.
60-persistent-input.rules creates persistent symlinks for input
devices, and 95-udev-late.rules enables udevmonitor.
* 60-persistent-storage.rules: Replace ATTRS{../removable} with just
ATTRS{removable} on partition devices. Replace ATTRS{removable}
with ATTR{removable} on whole-disk devices.
2006-09-20 Bryan Kadzban <bryan@linuxfromscratch.org>
* 05-early.rules: Missed a rule in the last change. ENV{PHYSDEVBUS}
in the rule that waits for the "bus" symlink should be replaced by
SUBSYSTEMS.
2006-09-20 Bryan Kadzban <bryan@linuxfromscratch.org>
* Adapted rules to the new matches used in udev-098 and above (e.g.,
SYSFS becomes ATTRS). Prevents warnings, and support for the old
matches will be removed eventually. These rules will not work with
udev-097 and before!
* Fixed several bugs in the rules left over from previous udev
versions (missing commas, overwriting user symlinks using ="..."
instead of +="...", and matching against "*" instead of "?*").
* Renamed CHANGELOG to ChangeLog, started using pseudo-GNU-format
entries. (See standards.info; search it for "changelog" to get
the general gist.)
dnicholson - Jul 14, 2006
* Fixed usbdev PROGRAM so that it works with the BusyBox sh. Thanks
to Anthony Wright.
n/a - Jul 12, 2006
* Added options so temporary nodes are not created with device-mapper
* Adapted cdrom rules to identify CD-ROM drives correctly by adding
SUBSYSTEM=="block" test.
* Added simple 81-cdrom.rules file to set cdrom group ownership
n/a - Jun 07, 2006
* Removed nvidia rules
* Removed bug reporting rule
* Moved Debian-based persistent CD-ROM rules to contrib
* Adapted firmware rule to udev-093
n/a - May 15, 2006
* Part one of 25-lfs.rules rewrite
* Some minor tweaking of the layout
n/a - May 12, 2006
* Initial import of the udev-config directory.
* Reorganized and modularized the rules files.
* Added explanatory comments

The udev-lfs set of files is a customization of systemd.
In 2012, udev was merged with systemd and a build methodology
incompatible with LFS. These files extract the udev
code from systemd for LFS.
These files are distributed in the form of a tar file available
from the LFS file mirrors. The tarball is created with:
mkdir /tmp/udev-lfs-$VERSION
cp -av * /tmp/udev-lfs-$VERSION
tar -jcf /tmp/udev-lfs-$VERSION.tar.bz2 -C /tmp udev-lfs-$VERSION
Makefile.lfs - The main LFS Makefile. Builds and installs
udev from systemd sources.
makefile-incl.keymap - BLFS makefile for keymap and supporting files
makefile-incl.gudev - BLFS makefile for libgudev
makefile-incl.gir - BLFS makefile for GObject files
contrib - Useful rules from debian

Purpose of rules file:
Most of the rules installed by Udev itself create devices with the correct
properties. This file contains rules that have not been merged upstream yet.
Description of rules:
By default, Udev creates device nodes with UID 0, GID 0, and permissions 0660.
ISDN-related devices should be owned by the 'dialout' group, hence the following
rule (and similar):
KERNEL=="ippp[0-9]*", GROUP="dialout"
The RTC-related rules cause the setclock bootscript to be run as soon as the
RTC device has been created by Udev, meaning that times in log files, for
example, are as accurate as possible as quickly as possible.
A final word of caution: Any particular rule must be written on one line, and a
comma must separate each part of the rule.

This directory contains documentation for each rule file used in LFS.
Each .rules file should contain a corresponding .txt file in this directory,

.SH "DESCRIPTION"
.PP
udevd listens to kernel uevents\&. For every event, udevd executes matching instructions specified in udev rules\&. See
\fBudev\fR(7)\&.
.PP
The behavior of the running daemon can be changed with
\fBudevadm control\fR\&.
.SH "OPTIONS"
.PP
\fB\-\-daemon\fR
.RS 4
Detach and run in the background\&.
.RE
.PP
\fB\-\-debug\fR
.RS 4
Print debug messages to stderr\&.
.RE
.PP
\fB\-\-children\-max=\fR
.RS 4
Limit the number of parallel executed events\&.
.RE
.PP
\fB\-\-exec\-delay=\fR
.RS 4
Number of seconds to delay the execution of RUN instructions\&. This might be useful when debugging system crashes during coldplug cause by loading non\-working kernel modules\&.
.RE
.PP
\fB\-\-resolve\-names=\fR
.RS 4
Specify when udevd should resolve names of users and groups\&. When set to
\fBearly\fR
(the default) names will be resolved when the rules are parsed\&. When set to
\fBlate\fR
names will be resolved for every event\&. When set to
\fBnever\fR
names will never be resolved and all devices will be owned by root\&.
.RE
.PP
\fB\-\-version\fR
.RS 4
Print version number\&.
.RE
.PP
\fB\-\-help\fR
.RS 4
Print help text\&.
.RE
.SH "ENVIRONMENT"
