Much like for rfkill devices we should provide some stability regarding
enumeration order, hence include the stable bits of the device path in
the file name we store settings under.
Let's include the stable device path for the rfkill devices in the name
of the file we store the rfkill state in, so that we have some stability
regarding enumeration order.
As many laptops don't save/restore screen brightness across reboots,
let's do this in systemd with a minimal tool, that restores the
brightness as early as possible, and saves it as late as possible. This
will cover consoles and graphical logins, but graphical desktops should
do their own per-user stuff probably.
This only touches firmware brightness controls for now.

Otherwise, when a network device is renamed, systemd-sysctl is run twice
with the same network device name: once for ACTION="add" and once for
ACTION="move".
Partially revert 2b3c81b02f, which
tried to avoid inconsistent rules about when and how to create the
/dev/rtc symlink.
Instead of conditionally or not creating the /dev/rtc link at all,
now always create it with additional and more reliable udev rules.
First try to find the "system rtc" with the hctosys flag, if this
is not found, fall back to create the link for /dev/rtc0.
Our code now never actively searches for the "system rtc" it can
always use /dev/rtc.
The export of the RTCs hctosys flag is uneccesary, the kernel takes care
of the persistemt clock management itself, without any need for:
CONFIG_RTC_HCTOSYS=y
CONFIG_RTC_HCTOSYS_DEVICE="rtc0"
"Chaotic hardware platforms" without native kernel persistent clock
support will find the proper RTC with the logic rtc_open() without
the need for a custom symlink.
<heftig> kay: systemd commit 22582bb broke cups usb printing for me
<heftig> because the "lp" group isn't applied anymore
<heftig> SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ENV{ID_USB_INTERFACES}=="*:0701??:*", GROUP="lp"
<heftig> moving this line to the end of 50-udev-default.rules restores correct behavior, as it's after usb_id
The 'kmod' builtin, like the 'firmware' and 'uaccess' builtins, does not set
any variables, so don't use IMPORT.
Notice that this changes the behaviour slightly: the processing of subsequent
rules for the event that loads a module will no longer wait for the module
loading to finish. This is not expected to cause any problems, but we should
keep an eye on it.
The properties will still be set in the udev database, but they will not be used
for setting the interface names. As for the other kernel commandline switches,
we allow it to be prefixed by 'rd.' to only apply in the initrd.

HP iLO fw versions below 1.50 incorrectly report that HP iLO virtual
Kbd/Mouse supports remote wakeup. With the rules change in commit
3bfc7a97b1, the HP iLO was listed for
power control.
In iLO fw versions less than 1.50, the iLO Kbd/Mouse become unresponsive
once they are suspended. HP iLO fw versions 1.50+ correctly report that
they don't support remote wakeup, which makes the rules moot in any case.
Much like logind has a client in loginctl, and journald in journalctl
introduce timedatectl, to change the system time (incl. RTC), timezones
and related settings.
Commits 5e9eb156c and 32567f8 introduced persistent symlinks for input devices
with more than one interface. However, this does not ensure stability for the
"default" interface, i. e. with interface number 00 or a nonexisting one. If a
device with a higher interface number appears first, it'll claim the symlink
name without an interface number, and the "interface 00" device won't get any.
Fix this by creating the default symlink only for interface 00 or a nonexisting
one, so that we properly partition the two cases over the two rules.

All "btrfs" file systems will be registered with the kernel when they
show up.
Incomplete multi-device volumes will set SYSTEMD_READY=0, to prevent
access until the volume is complete and fully registered.
/dev/md0 appears as soon as the first component of the raid array is
added by incremental assembly rules. This is too early for systemd to
attempt to mount the device. The device should be considered plugged
after the raid array becomes active.

<arjan> can you open the 42-usb-hid-pm.rules file
<arjan> and go to line 46
<arjan> and tell me why ATTR{idProduct}="0002" only has one = and not two (e.g. == ) ?
<kay> arjan: yep

Some USB ports on external hubs may be reported as "fixed". We only want
to auto-enable this on ports that are internal to the machine, so check
the parent state as well.
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.
Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.
The bits that used to be MIT continue to be MIT.
The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.
