Currently when initqueue timeout, it span the console with
"dracut-initqueue timeout - starting timeout scripts", which isn't very
helpful as we still don't know what actually happened. Try to improve
this by print what is actually being waited.
Besides, only print "starting timeout scripts" when there are
actual timeout scripts to use.

if the kernel argument rootflags is set, then dracut will
not parse the rootfs fstab and rootfsck wil not be set.
if the filesystem can be fsck'ed then its unmounted,
and an entry to the local fstab is written, omitting the last
field.
mounting /sysroot using fstab will then fail.
This change makes sure that the filed is always written.

Currently systemd will always start the tracking service, it will
exit early if rd.memdebug<=3 so there is no issue here, but it
leave a message of: "Started Memstrack Anylazing Service.".
Better to avoid such message if it's not used.

The iSCSI configuration is started after dracut checks for resume,
so we run into a timeout here. Additionally it's questionable if
resume on iSCSI makes sense (or is even supported on the platform).
Same holds true for Network Block Devices and FcOE, cover those as well

Add support to boot from an NVMe over TCP device.
Example of supported command line formats:
nvme.discover=tcp:192.168.1.3::4420
nvme.discover=tcp:192.168.1.3 # will use 4420 as default svcid
- Create is_nvmf() function to handle all fabrics types
- Fix parse_nvmf_discover() to correctly use the default values
- Auxiliary function to validate an IP connection
- Fix inverted result for getargbool when reading "rd.nonvmf" command line parameter
Requires rd.neednet=1
Requires adding/replacing STARTMODE in /etc/sysconfig/network/ifcfg-ethX to "nfsroot"
to avoid shutdown hanging in initiator

ipv6 addresses need square brackets, otherwise the iscsi discovery and log-in,
which adds the iscsi port after another colon will get confused and fail.
After changing the kernel command line, the cmsifup script calls ifup
to activate the interface. However, ifup is only available in the
network-legacy module; when using the network-manager module, we
should regenerate connections according to the command line; then
later NM will be run and will activate the device.
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.
Fixes: #772
/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.
