Most rpc services are not needed for NFSv4, so skip these components
to save space. rpc.idmapd is still needed in case of
nfs4_disable_idmapping is set to 0.
Since commit ff70adf873ef ("initrd: save hostname to a file in /run"),
the initrd generator of NetworkManager parses the hostname from 'ip='
options of the kernel command line and writes it to
/run/NetworkManager/initrd/hostname.
When that file exists, set the kernel hostname.
In presence of multiple hostnames in the command line, the last one
wins. Hostnames from command line always have precedence over ones
received through DHCP. This is a bit different from the legacy network
module that gives higher precedence to the hostname (from DHCP or
command line) of the last interface that is brought up, which depends
on the udev order.
In commit 49c4172 all shell based memory tracing functions are removed,
there are some left over. Remove them as well.

With memstrack module, rd.break may not work because the hook scripts
are sourced, not executed, so the exit call will make pre-pivot queue
exit early. See 98dracut-systemd/dracut-pre-pivot.sh, everything after
"source_hook cleanup" will be ignored.
Replace with return instead.

The first line in crypttab with a "force" option causes all subsequent
lines to be included as if they also had it set because the variable
used to track it is not reset between loop iterations. So fix that by
just setting it to empty before the check for the force option.
If a crypto kernel module changes from compiled in to module, the
encrypted disk might fail to open, because the kernel module was
not included in the initramfs.
This patch tries heuristically to catch such modules.
Fixes https://github.com/dracutdevs/dracut/issues/706
This feature could be off loaded to memstrack, which have better
accurecy, better performance, and have more detailed tracing features.
Also simplify make_trace_mem a bit.
And currently rd.memdebug=4 is unstable, fails from time to time.
Install libnss_dns.so and libnss_mdns4_minimal.so plugins for the Name
Service Switch (NSS) functionality of glibc so that name resolution
through /etc/resolv.conf and mDNS works in the initrd.

/etc/vconsole.conf must be installed always, even in generic initrds, not only host-only ones.
systemd-vconsole-setup is run at initrd stage and expects either /etc/vconsole.conf or kernel cmdline options to exist.
I have also proposed a change in systemd-vconsole-setup that makes it behave better if /etc/vconsole.conf does not exist:
https://github.com/systemd/systemd/pull/15479
But it is just a fallback. If /etc/vconsole.conf does not exist in initrd and if that patch is applied on systemd,
then the default consoel font is set despite the one being set in /etc/vconsole.conf and this setting is inherited
when new TTYs are opened. This leads to full ignorance of settings in /etc/vconsole.conf.
It is incorrect, and that is why this file must be copied to initrds always, but not only on host-only initrds.

According to POSIX.1-2017, 2.6.2 Parameter Expansion:
${parameter%[word]} [...] The word shall be expanded to produce a
pattern.
This means if word contains variables that itself contain special
characters like asterisks or backslashes, these are treated as pattern
characters unless the variable is quoted. Try e.g. the following example
in bash, dash or (busybox) ash:
i='a\c'; j='\'; echo "${i%$j*}"
This prints "a\c" because "$j*" is expanded to "\*", escaping the
asterisk. In contrast,
i='a\c'; j='\'; echo "${i%"$j"*}"
produces the expected result "a" because the backslash is not specially
treated any more after quoting.
The quotes that this commit adds have been previously removed in commit
f9c96cf56f, citing issues with busybox
hush without further specifying the actual error. I tested a recent
busybox build (upstream commit 9aa751b08ab03d6396f86c3df77937a19687981b)
and couldn't find any problems. Note that the above example always
produces "a\c" in hush regardless of quoting $j, making hush unsuitable
for use with dracut, but using quotes in parameter expansions generally
works.
The unquoted variables break the "rd.luks.uuid/name" kernel command line
options in dracut 050 because
str_replace "$luksname" '\' '\\'
in modules.d/90crypt/parse-crypt.sh is not able to escape the
backslashes any more, see GH-723, GH-727: backslashes in the
systemd-cryptsetup@.service unit name stay unescaped for use in udev
(cf. commit 0f6d93eb9d), leading to
failures in starting the unit.
This partially reverts commit f9c96cf56f.
qeth device may have a different IP for each boot, so the rd.ifname=
option will no longer work. So for znet device, introduce a
rd.znet_ifname= options, to subchannel id instead of MAC address as the
identifier and rename the interface.

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
```
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.
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.

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.
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.

The original behavior of $env{INTERFACE} was undocumented and changed in
the recent udev versions, breaking the ability to bring up networking
reliably. Switching to $name directive should fix this issue.

Previously, we were doing `setup_net` from `ifup` for any setup that
wasn't DHCP, since those are already taken care of by `dhclient-script`.
The issue is that the case-statement we use to detect this doesn't catch
options like `ip=dhcp,dhcp6`.
Fix this by reworking the logic here to just check if a
`setup_net_$netif.sh` hook exists. If so, then we know that `setup_net`
will be called for this interface later.
This was causing issues in RHCOS which now ships with `ip=dhcp,dhcp6` to
support IPv6 environments[1]. The code here would make us do `setup_net`
pre-emptively which IIUC would then cause the initqueue to finish
earlier even if we had more udev netif events to process.

This reverts commit c603419030.
wait_for_ipv6_dad_link is only called from dhclient script,
so the original intent "wait for IPv6 RA if using none/static IPv6 assignment"
does not seem to be correct.
Anyway, this brings an issue on isolated networks, where you don't
have any routes outside. dhclient-script hangs on this check
and after it times out, dhclient is able to set the address normally.
