some programs e.g. systemd-journald expect a directory in /var/log as
the marker to do some actions. Here journald tries to flush
/run/log/journal to /var/log/journal, if the directory is seen.
/var/log is now a symlink to /run/initramfs/log.
If the user pressed ESC while checkisomd5 runs the media check, it will
exit with "2". Previously that would mean, that the media check was not
successful.
The multipathd package might install a service and a socket
file. Using the original service file from the installed
system without the socket file triggers a bug in systemd,
causing systemd to crash.
As we don't actually need to socket file in the initrd we
should be installing our own service file which does not
reference the socket file at all.

The device handler modules need to be loaded early during boot
to avoid I/O errors being printed to the system log.

multipathd is using pthreads, which require libgcc_s for
pthread_cancel to work. Without it multipathd might crash
with SIGABRT.

udevd will these days default to 'info' logging and thus will
often print out the 'starting version nnn' message (which is
logged at level 'info'), thus spamming the console, even on
'quiet' boots.
We generally expect a udev log level of err (the old default
from pre-October 2013) so we should set that explicilty before
launching udevd in order to suppress the spurious 'info' message.
As we are using the environment variable approach anyway, we
may as well use this method rather than setting the log level
later via udevadm control commands when rd.udev.info/debug are
given on the kernel command line.
The enviroment variable has been around since udev 6b493a20e1
around 2005 so should be safe to use in all cases without version
checks.
It is not available to valid the customize dhcp config

Dracut uses the default follow config to construct the initramfs.

Copy the customize config to make the config availably in the

The usb_storage, nvme and sdhci_acpi modules are discovered with the
block_module_filter so there's no need to explicitly list them here.

The synthetic keyboard of a Gen2 Linux VM doesn't work before the
hyperv_keyboard module is loaded. Without it, we can't cancel the media check
phase if boot with rd.live.check option.
Gen1 Linux VM doesn't have the same issue because the host emulates the legacy
i8042 keyboard for Gen1 VM.

Up until now, _check_shutdown() returns true if at least one of
the shutdown hooks succeeded. Change this to only return true if
*all* succeeded. To prevent an infinite loop, introduce an upper
bound of 40 iterations.
When you define the gateway for an interface, dracut sets it up with:
ip route add default via $gw dev $netif
If a default route is already set (e.g. if you have multiple NICs), this
will fail with the message "RTNETLINK answers: File exists".
So, if your first NIC isn't usable as a default route
Using "ip route replace default" instead allows ifup/dhclient-script to
correctly change the default route to the new interface.
loginstall specifies a directory, in which dracut-install records all
files, which were installed from the host system to the initramfs.
Use case is e.g. to create a list of packages to watch for updates, to
maybe trigger a recreation of the initramfs.
