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.

|
||||
2017-10-27 <bdubbs@linuxfromscratch.org>
|
||||
* 83-cdrom-symlinks.rules: Adjust test for writable root directory.
|
||||
|
||||
2014-03-02 <bdubbs@linuxfromscratch.org>
|
||||
* Makefile.lfs: Remove build procedures leaving only LFS rules
|
||||
|
||||
2014-02-16 <bdubbs@linuxfromscratch.org>
|
||||
* Makefile.lfs: Adjust warning flags. Adjust linking rules to
|
||||
allow build with util-linux in LFS's /tools directory.
|
||||
|
||||
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 add cusom udev rules
|
||||
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

tar -jcf /tmp/udev-lfs-$VERSION.tar.bz2 -C /tmp udev-lfs-$VERSION
