b5df2eabf3 rules: allow systemd to manage loop device partitions
SYSTEMD_READY is currently set to 0 for all loop devices (loop[0-9]*)
that do not have a backing_file. Partitioned loop devices (ex. loop0p1),
however, are matched by this rule and excluded by systemd even though
they are active devices.

This change adds an additional check to the rule, ensuring that only
top level loop devices (loop[0-9]+$) are excluded from systemd.

49804365ea udev: keyboard - also hook into "change" events
Re-apply the keymaps when "udevadm trigger" is called. Hooking into
"add" only would just remove all keymap content from the udev database
instead of applying the new config.

cd31d1884f rules: update qemu hid rules
Update comment to be a bit more specific.

Change match to blacklist the serial number of the broken devices
instead of whitelisting the serial number of the fixed devices.
This allows to do something useful with the serial number in the
future.

fc6c7fe9be getty: Start getty on 3270 terminals available on Linux on System z
Add the first 3270 terminal device that is associated with the Linux preferred
console to the list of virtualization consoles.  This is required to
automatically start a getty if the conmode=3270 kernel parameter is specified
for Linux on z/VM instances.  Note that a queued upstream patch also enable
the 3270 terminal device if it is associated with the Linux preferred console.
How

To successfully start agetty on a 3270 terminal, a change in the agetty
parameter order is required.  Previously, agetty would started like this:

    /sbin/agetty --keep-baud 3270/tty1 115200,38400,9600 TERM

The agetty program interprets the "3270/tty1" as baud rate and fails to start
with the "bad speed: 3270/tty1" error message.  Fixing this in agetty is more
complex rather than reordering the command line parameters like this:

    /sbin/agetty --keep-baud 115200,38400,9600 3270/tty1 TERM

According to agetty sources and "agetty --help", agetty accepts the "tty",
"baudrate tty", and "tty baudrate" specifications.

P.S. The "tty: Set correct tty name in 'active' sysfs attribute" introduces
     a change to display the terminal device which is associated with the
     Linux preferred console.  This change helps to let systemd handle this
     particular case only.  Without the changes of this commit, no additional
     3270 terminal device can be managed by systemd.

98b2f766b2 gpt-auto-generator: rename root device node symlink to /dev/gpt-auto-root
Before it was placed in /dev/disk/by-id, which makes it a bit too much
API. However, it's mostly an implementation detail for now, hence move
it out of the stable block device dir.

99bd4af0c7 udev: add zram to the list of devices inappropriate for symlinks
udev seems to have a race condition with swapon to see which can open
/dev/zram0 first, causing swapon to fail. Seems to be most noticeable
on arm devices one out of every 7 times or something.

07901fc142 s390/getty-generator: initialize essential system terminals/consoles
Ensure to start getty programs on all essential system consoles on Linux on
System z.  Add these essential devices to the list of virtualization_consoles
to always generate getty configurations.

For the sake of completion, the list of essential consoles is:

  /dev/sclp_line0 - Operating system messages applet (LPAR)
  /dev/ttysclp0 - Integrated ASCII console applet (z/VM and LPAR)
  /dev/ttyS0 - Already handled by systemd (3215 console on z/VM)
  /dev/hvc0  - Already handled by systemd (IUCV HVC terminal on z/VM)

Depending on the environment, z/VM or LPAR, only a subset of these terminals
are available.

See also RH BZ 860158[1] "Cannot login via Operating System Console into RHEL7
instance installed on a LPAR".  This bugzilla actually blocks the installation
of Linux on System z instances in LPAR mode.

0a8da8305a rules: load path_id on DRM devices
The path_id-builtin provides useful unique aliases for DRM devices. If we
want to configure DRM render-nodes for compositors, we want to avoid
storing the whole sys-path in configuration files. Hence, allow users to
store the short PATH_ID instead.

Load path_id-builtin unconditionally on DRM devices now to always provide
this alias.

daeb71a36a udev: link-config - move naming policy from udev rules
This introduces a new key NamePolicy, which takes an ordered list of naming
policies. The first successful one is applide. If all fail the value of Name
(if any) is used.

The possible policies are 'onboard', 'slot', 'path' and 'mac'.

This patch introduces a default link file, which replaces the equivalent udev
rule.

af6f0d422c udev: add network link configuration tool
This tool applies hardware specific settings to network devices before they
are announced via libudev.

Settings that will probably eventually be supported are MTU, Speed,
DuplexMode, WakeOnLan, MACAddress, MACAddressPolicy (e.g., 'hardware',
'synthetic' or 'random'), Name and NamePolicy (replacing our current
interface naming logic). This patch only introduces support for
Description, as a proof of concept.

Some of these settings may later be overriden by a network management
daemon/script. However, these tools should always listen and wait on libudev
before touching a device (listening on netlink is not enough). This is no
different from how things used to be, as we always supported changing the
network interface name from udev rules, which does not work if someone
has already started using it.

The tool is configured by .link files in /etc/net/links/ (with the usual
overriding logic in /run and /lib). The first (in lexicographical order)
matching .link file is applied to a given device, and all others are ignored.

The .link files contain a [Match] section with (currently) the keys
MACAddress, Driver, Type (see DEVTYPE in udevadm info) and Path (this
matches on the stable device path as exposed as ID_PATH, and not the
unstable DEVPATH). A .link file matches a given device if all of the
specified keys do. Currently the keys are treated as plain strings,
but some limited globbing may later be added to the keys where it
makes sense.

Example:

/etc/net/links/50-wireless.link
[Match]
MACAddress=98:f2:e4:42:c6:92
Path=pci-0000:02:00.0-bcma-0
Type=wlan

d1f0e886e1 rules: remove pointless MODE= settings
Changing the default MODE= for the group accessi, but not specifying
a GROUP= does not provide anything.

It disables the default logic that the mode switches to 0660 as soon
as a GROUP= is specifed, which make custom rules uneccesarily complicated.

3731acf1ac backlight: add minimal tool to save/restore screen brightness across reboots
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.

67fb4482ac always unconditionally create /dev/rtc and use it internally
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.

2b3c81b02f do not create /dev/rtc symlink, let systemd search for it if needed
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.

f4fbb8be14 udev: builtin - use RUN rather than IMPORT for loading modules
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.
