Previously, dracut would only copy the first one found. However,
with legacy maps for some locales around, there is a chance we
pick the wrong one. Pick all matching keymaps instead

If no iscsi session information can be retrieved from the firmware
then skip the iscsi attachment and allow the boot process to continue.
Ensure the timeout scripts don't hit their timeout waiting for
/tmp/iscsistarted-firmware to be created.
This will allow a common image to be used for servers with both a
local and iscsi root with rd.iscsi.firmware set.
Some of the more complex devices now need rpmsg and hwspinlock in the early boot
process to start, and these to the initrd, and pull in usb/misc because
apparently non standard usb hubs are a thing.

Type=oneshot, as currently set in dracut's emergency service file,
causes an awkward situation if emergency mode is entered e.g. because
of a root device timeout, and the root device appears later because it
just has taken longer than the timeout. In that situation, my
expectation (backed by past positive experience) is that the user should
be able to simply exit the emergency shell and resume normal boot.

Failed to start default.target: Transaction is destructive.
(system keeps idling from this point on, user has no chance to
do anything).
This results from the combination of two effects:
1) initrd-root-fs.target sets "OnFailureJobMode=replace-irreversibly",
2) emergency.service's Type=oneshot causes the start jobs for both
emergency.service and emergency.target to persist while the user is in
the emergency shell.
When the shell is exited, systemd tries to isolate "initrd.target"
again, but this fails with "the transaction is destructive" error
because of the still pending jobs.
This patch fixes this by changing the Type of "emergency.service" from
"oneshot" to "idle".
JobRunningTimeoutSec now affects how long can start jobs for device
units stay in the "running" state. Disabling default job timeout via
JobTimeoutSec=0 doesn't disable running state timeout. We need to set
running state timeout as well.
Note that doing this the other way around has effect on generic timeout,
i.e. disabling running state timeout disables generic timeout. But doing
it this way we would create implicit dependency on fairly new
systemd-234. However, by setting both options we don't create dependency
on specific systemd version.
A LUKS root volume with a detached header on a device without partitioning will not have a UUID and will not have an attribute ENV{ID_FS_TYPE}=="crypto_LUKS".
Therefore, several areas need to be addressed: identification of the LUKS device, inclusion of entries within crypttab, and provision of the detached header file.
- Added support for an option (4th column: "force") in /etc/crypttab to force the inclusion of the entry in the initramfs version (avoiding the fs type test).
- Added support for an option (4th column: "header=/path/to/file") in /etc/crypttab to provide a path to a detached header file embedded within the initramfs.
- Added ID and PARTUUID support to the device (2nd column) in /etc/crypttab (complementing the existing UUID functionality).
- Added cmdline support to indicate LUKS device ("rd.luks.serial=") that refers to the attribute ENV{ID_SERIAL_SHORT}.
Tested successfully on Void Linux (x86_64 musl) (no systemd) with a LUKS root volume accessed with a keyfile and using a detached header.
Not tested on systemd, or on a LUKS root volume with a passphrase rather than a keyfile.
Some Combined Network Adapters(CNAs) implement DCB protocol
in firmware, it is recommended that do not run software-based
DCB or LLDP on CNAs that implement DCB, but we have to start
the lldpad service anyway(there might be other software DCB).
If the network interface provides hardware DCB/DCBX capabilities,
the field DCB_REQUIRED in "/etc/fcoe/cfg-xxx" is expected to
be set to "no".
We met an issue on "QLogic BCM57810" with DCB firmware support,
and found dracut still generated "fcoe=<mac>:dcb" which caused
kdump boot failure when using that fcoe dump target.
This patch parses /etc/fcoe/cfg-xxx to detect DCB_REQUIRED="no",
and force "nodcb" if it is the case.
Also improved some coding style in passing.

The MTU is only being set on the slave devices and the MTU of the
bonding master is not being updated. This updates the bonding master and
also changes the MTU on the slaves as expected.

kerneldirlen is used to modify absolute path returned by
kmod_module_get_path() while it is calculated on user-supplied
--kerneldir argument which can be a relative path.
Use kmod_get_dirname() to convert user-supplied path to the same format
as used by kmod_module_get_path().
This also allows to get rid of now useless strcmp checks that seem to
imply that /lib and /usr/lib are linked which is not always true.
Prior to this commit, the MTU setting was applied to a bond slave
interface. In older versions of the Linux kernel, this setting
propagated to the bond master and the other bond slaves associated with
the master. In recent versions of the kernel (observed in Linux 4.12),
increasing the MTU of a slave does not automatically increase the MTU of
the master. This allows for more flexibility but requires the MTU of
the master to be changed manually.
Ideally, the MTU setting should be applied to the bond master and the
setting will propagate to the bond slaves, since the slaves are required
to have a MTU that is greater than or equal to the bond master.
systemd sets /proc/sys/kernel/core_pattern to use systemd-coredump.
However, systemd-coredump is missing from initrd, making dumping
the core in initrd impossible by default.

Currently in Fedora/RedHat dracut installs its fedora.conf.example
as the default config file, in which sysloglvl is set 5. This leads
to maxloglvl=5 in dracut calls, making unnecessary lsinitrd calls
during initramfs builds by kdump.
This patch disables lsinitrd logging when --quiet option is given,
which is controlled by maxloglvl only before. This will speed up
dracut image building as the following if --quiet is used in kdump:

In case of "--no-hostonly-default-device", we do not need
the root device, thus add this check.
Also fixed the stale "root_dev" export.

Kdump doesn't need default host devices like root, swap, fstab, etc,
we only care about the dump target which can be added via "--mount"
or "--add-device". We met several issues that kdump kernel failed
due to one of those host devices added by dracut, additionally, the
needless devices(e.g. LVM) consume some appreciable amount of memory
which is more likely to cause OOM under memory-limited kdump.
So this patch introduced "--no-hostonly-default-device" to avoid
adding those default devices as host_devs.

SSH uses passwd database and thus need various NSS plugin libraries,
depending upon setting in nsswitch.conf.
SSH binary fails within the dracut environment without the libraries:
#:/ ssh
No user exist for uid 0
In the module-build-service, we have pieces of dracut provided by different
modules ("base-runtime" provides most functionality, but we need
dracut-network in "installer". Since these two modules build with separate
dist-tags, we need to reduce this strict requirement to ignore the dist-tag.
