When in hostonly mode, 95fcoe module will still be installed even there
is no FCoE hostonly device. So use the new block_is_fcoe helper to check
for hostonly device in hostonly mode, avoid installing unneccessary module.

If fcoe module is loaded, the initramfs will always try load libfcoe
and bnx2fc, so also ensure they are installed if needed.

Library file modules.d/99base/dracut-lib.sh contains initialization code
that makes sure certain directories and links are created when a system
runs from the produced initramfs. This file is normally sourced only
from initramfs scripts. However, modules.d/99base/module-setup.sh
includes it also when an initramfs image is being created to gain access
to some of the functions in this library. This can result in creating
unexpected directories and links on the current root file system when
the dracut command is executed.
For instance, during a system installation when dracut is invoked to
create an initial initramfs, the target sysroot might not contain
directory /run/initramfs but have /var/log. This situation results in
the code in modules.d/99base/dracut-lib.sh creating an unexpected link
/var/log/log that points to /run/initramfs/log. This link is then also
present on the installed system.
The patch fixes the problem by skipping the described logic in
modules.d/99base/dracut-lib.sh when the PREFIX variable is non-empty
which indicates that a target initramfs is being prepared. The variable
is set by modules.d/99base/module-setup.sh prior to including
dracut-lib.sh.
Sometimes, systems have more elaborate backends in nsswitch.conf,
the complexity of which we do not want in the initrd. SUSE systems
with atomic for instance, where those files may also reside in /usr/etc.
With this change, the unavaiable nsswitch.conf backends will be silently
ignored, and we still end up with all the information we need.

dracutinstall picks up interpreters and includes bash despite
the users' wishes or expectations, as modules should not require
bashisms at runtime.
Fixes#951
This should've been part of #964. As mentioned there, the
`initrd-cryptsetup.target` approach was reverted in the end, and we went
back to relying in `remote-cryptsetup.target`:
https://github.com/systemd/systemd/pull/17467
So we do need to ship the enablement symlink for it.
For strict hostonly mode, only install currently loaded modules instead
of a bunch of driver that may not be needed.

Currently when network is enabled, dracut will install all network
drivers that are currently loaded, but some time only one NIC is needed
for the initramfs.
So for strict hostonly mode, add a --hostonly-nics option, user can
provide a list of NICs to be enabled, and only needed drivers for
specifed NICs will be installed so save space.

This was added in https://github.com/systemd/systemd/pull/17149 and is
the designated cryptsetup target for all encrypted volumes that need to
be opened in the initrd.
So it effectively replaces `cryptsetup.target` and
`remote-cryptsetup.target` there. I've removed the latter since it was
added recently (by me) in #930, but kept `cryptsetup.target` since we've
been shipping it for a long time now.
With commit 3c8c807, /run/initramfs/isoscan and /run/initramfs/live
mountpoints are unmounted upon rd.live.ram boots. Save a link to
the iso-scan device in /run/initramfs/isoscandev to easily remount
the source, if desired.
This is a plain and simple hack around dependency issues between dracut
and systemd.
When using Tang-pinned LUKS root devices, we want to rely on
`systemd-cryptsetup@.service` to unlock it. However, that service only
runs `After=remote-fs-pre.target`, while `dracut-initqueue.service` has
`Before=remote-fs-pre.target` (which makes sense because we don't want
to attempt networked root devices before networking is up).
However, the rootfs-generator here wants to make sure that the root
device exists *before* exiting the initqueue via an initqueue/finished
"devexists" hook. This will never work though because by design
`systemd-cryptsetup@.service`, which unlocks the root device, won't run
until after we exit.
So we have a dependency cycle:
initqueue -> devexists hook -> root device ->
systemd-cryptsetup@.service -> remote-fs-pre.target -> initqueue
There's no clean way to break this. The root issue is that there's no
way right now to split sequencing of systemd services across the
initqueue/online and initqueue/finished events because it's all bundled
in a single service. (The deeper root issue of course is that we have
two init systems. :) ).
Here we do a tactical fix: if there's a `systemd-cryptsetup@.service`
instance, let's assume it's for the root device and skip waiting for it
to show up if it depends on `remote-fs-pre.target`.
dracut feeds whatever it receives in password field of
crypttab(5) to `cryptsetup -d`, treating them as plain-text key file.
Meanwhile, dracut treats the key file from `rd.luks.key` differently,
by have some special rules to decrypt those key files that has extension of
`gpg` and `img`.
Let's begin to treat them the same.
This is a backward-incompatible change for those people
that uses plain-text key-file that has extension of `gpg` and `img`.
However, those setup is questionable to begin with.
In the case of the s805x the drivers/hwmon directory contains the
scpi_hwmon kernel module.
On a running system, lsmod would output the following dependencies:
arm_scpi 24576 2 clk_scpi,scpi_hwmon
It means that if the clock driver is bundled in the initramfs it will
bring arm_scpi. But if scpi_hwmon is missing the scpi will be incomplete
and it can lead to crashes.
When the hwmon is bundled, no crash occurs

Some filesystem (e.g. ZFS, and btrfs subvolumes) don't use block
devices. Should they be mounted as `/`, `find_root_block_device`
yields nothing, hence dracut will append this problematic argument
to kernel cmdline:
root=/dev/block
On a machine that employ root ZFS on LUKS, which was setup with
an OpenPGP-encrypted key file, this argument renders that machine
unbootable. Remove that `root=/dev/block` manually could boot the
machine.
Let check if that device is a block device before write down `root`
argument. This is consistent with the check for block device in
`find_block_device`.

D-Bus doesn't run in the initrd, so our usual trick of activating
custom systemd services from udev doesn't work.
So add a rule to create initqueue entries for each possible

Always add the nvmf.discover parameters to /etc/nvme/discovery
when parsing the dracut commandline, and rely on NVMe autodiscovery
when no parameters are given.
And modify the syntax to use a comma ',' as a separator for nvmf.discover
as the semicolon ':' is already used for the FC-NVMe transport address format.

Introduce prefix `keysource:` for the values of `rd.luks.partuuid`,
`rd.luks.serial` and `rd.luks.uuid`.
If specified, ask for passphrase instead of waiting for keydevs to come
online.
In some cases, user only want to include the watchdog module, not the
wdctl or any other userspace helper. For example, systemd have a
RebootWatchdogSec option that use watchdog to prevent reboot hangs. And
it can help prevent machines hangs when reboot directly within the
initramfs stage. So split the module installation to a standlone module.
Also when watchdog-module get included, install driver for all loaded
watchdog instaed of only install driver for active watchdog. Both
watchdog and watchdog-module return 255 in check(), so it's enabled only
when manually included, the watchdog may get configured/activated later.

systemd lets stdout go to journal only. Usually, this is desired
behavior to ensure that plymouth does not get disrupted.
However in the 01fips case, the system has to halt when the integrity
check fails to satisfy FIPS requirements. So the user will not be able
to inspect the journal.
As this is special to the fips module, we introduce a fips_info() which
works like info(), but deviates the output to stderr when running with
systemd.
