Add support for 'rd.multipath=default' for using the default
configuration on boot. The intended purpose for this is to help support
ostree-based image boots from multipathed devices (such as Fedora and
Red Hat CoreOS).
`dasd.conf` needn't be present on system even if modules have been loaded.
Check if file exists to avoid error message during kernel update
```bash
dracut-install: ERROR: installing '/etc/dasd.conf'
dracut: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.YvVRx5/initramfs -H /etc/dasd.conf
```
The fix in aed52a6cfb43ebea372328fd5837c1f341c3f0df does not
work (second line will be ignored on override), so expand the implicitly
defined rule and add them there.
Emit a warning about possible misconfigured configuration files, where
the spaces around values are missing for +=""
Better report a possible source of problems. We can fix annoying false
positives later.
In either case:
- encrypted device is decrypted, udev will trigger device changes again,
- multiple encrypted device,
cryptroot-ask will run multiple time, then report:
> mkdir: cannot create directory '/run/cryptsetup': File exists
Pass `-p` into mkdir to ignore that warning.
Ability to use `$TMPDIR` was introduced in bc1e69b but
causes the `--tmpdir` option on the command line to be
ignored. Switch to only using `$TMPDIR` if `--tmpdir`
wasn't specified.
In this case we want to cover three cases
1) ip_address:ip_address
2) number:macaddress
3) :macaddress
We consider something an IPv6 address if it starts with number and
contains ":", but IPv6 addresses are in hexa.
The network-manager command line hook must install a
initqueue/finished hook to ensure that nm-run.sh is executed when
there are network connections to activate.
Fixes: #694
Use environment variable TMPDIR (typically /run/user/$UID) as default
temporary directory, if available. This should be more private
location than /var/tmp. Path specified with --tmpdir is takes
precedence over TMPDIR and /var/tmp is still used as last resort if
neither TMPDIR is set nor --tmpdir is used.

dracut.sh already doesn't call fsfreeze if the output file is on
the root file system. For btrfs, however, this is not sufficient.
Because fsfreeze is a superblock operation, and all btrfs subvolumes
share the same superblock, fsfreeze may freeze the entire system
if the subvolume on which the output file is written and / are
subvolumes of the same file system. Avoid this by comparing file
system UUIDs for btrfs.
Fixes: de576db3c2 ("call fsfreeze(8) on /boot to flush initramfs data & metadata to media")
Detection of persistent memory devices works mostly out of the box
already. Only the "provider" modules for ndbus devices, which are responsible
to extract information of available NVDIMM devices and their configuration
from system firmware, are only indirectly linked into the module stack.
Examples for such modules are nfit.ko, nd_e820.ko, and virtio-pmem.ko.
Add a module that resolves these dependencies.
With GNU Make 4.3 on both ArchLinux, and VoidLinux,
GITVERION is always empty because of bad substitution.
Change '\#' to simply '#' can fix it,
but we don't need that complation.
We can merge DRACUT_MAIN_VERSION and GITVERSION into DRACUT_FULL_VERSION.
Because, GITVERSION will be attached back to DRACUT_MAIN_VERSION in all
situation.
While we're at it, detect if we're in git worktree by:
limiting GIT_CEILING_DIRECTORIES to parent directory of
dracut's top level directory; instead of checking for .git directory,
in order to support git-worktree, in such case, .git will be a file, see
gitrepository-layout(5)
DRM drivers are filtered for drm_crtc_init symbol,
but not all drivers use it. Especially, cirrus driver
doesn't use it since Linux 5.2.
The practical result is text plymouth theme instead of graphical when in qemu.
Fix it by looking also for drm_dev_register symbol.

Currently there is no usb support on RPi4 in the
initrd phase as the pcie-brcmstb module is missing.
If part of the boot is handled from a USB stick
(e.g. with Ignition), the stick cannot be accessed.

systemd provides its own cryptsetup facilities, and the
cryptsetup binary might not even exist, failing
to execute the discard flag processing.
Fixes#602
Debian mkinitramfs does not create the file 'early_cpio', so detection
of additional cpio images fails and only the first cpio is listed.
I checked some Arch and Gentoo initramfs files and these didn't have
'early_cpio' either, but they also have only one cpio part.
Fix this so that if check for 'early_cpio' fails, check if firmware
files ('/kernel/*/microcode/*.bin') exist.
