systemd sets /proc/sys/kernel/core_pattern to use systemd-coredump.
However, systemd-coredump is missing from initrd, making dumping
the core in initrd impossible by default.

In case of "--no-hostonly-default-device", we do not need
the root device, thus add this check.
Also fixed the stale "root_dev" export.

SSH uses passwd database and thus need various NSS plugin libraries,
depending upon setting in nsswitch.conf.
SSH binary fails within the dracut environment without the libraries:
#:/ ssh
No user exist for uid 0
The dracut network module is only supposed to be used for wired interfaces
but if driver modules for wireless devices are wrongly copied, these will
be loaded and the available interfaces brought up.
If the rd.neednet=1 command line parameter is used, dhclient will attempt
to request an IP address for the interfaces and these requests will fail.
But other dracut modules that depend on the network to be settled, will
have to wait for the DHCP requests to timeout. Which can be a lot of time
since the dhclient default timeout value is 60 seconds.
Instead of trying to blacklist all possible kernel modules for wireless
devices, only bring up network interfaces if these are for wired devices.

We tell dhclient to name 121 option "classless-routes",
but in dhclient-script we parse classless_static_routes.
So either have to change the configuration or the script.
And since dhclient uses by default classless_static_routes,
let's change the configuration
hardcoding the wwid of the drives in the initramfs causes problems
when the drives are cloned to a system with the same hardware, but

Support booting from USB media with NTFS filesystem (optionally),
which removes the FAT32 related 4 GB file size limit for LiveOS/
squashfs.img (and any other file on the same USB media).
On s390 BOOT_IMAGE only denotes the number of the boot record that
was selected in the bootloader and not the path to the kernel image.
Also only bail out, if the kernel hmac checking relies on that path.
blkid is not available when this function is called, so block_uuid.map is put into
the initrd, mapping block devices from /etc/crypttab to UUIDs.
This fixes a bug where udev rules were created by mistake as crypttab_contains()
returned false for devices specified by path in /etc/crypttab which resulted in
error messages during boot.

Previously our dhclient-script expected that $new_classless_static_routes
will have all values separated by a whitespace. But at least on F25
dhclient will put there the destination descriptor in the same format
as it is used by ISC dhcp-server.
For example:
new_classless_static_routes=32.10.198.122.47 192.168.78.4
while our current code expects
new_classless_static_routes=32 10 198 122 47 192 168 78 4
So let's just accept both of these formats by adding "." to IFS.

When NPIV is enabled and the allow_lun_scan parameter is set to 'Y'
the HBA will initiate a LUN scan automatically, so there is no need
to specify the WWPN and LUN number manually.

For creating dynamic udev rules parse-dasd.sh look for the device
type in sysfs, which of course does not exist if cio_ignore is
active. So first enable the device before checking.

'for_each_host_dev_and_slaves' would stop at the first found
device, so the cmdline() call would never list all required
devices. Use 'for_each_host_dev_and_slaves_all' instead and
filter out duplicates.

Setting and unsetting the IFS variable is tricky. To be on the
safe side we should always reset the IFS variable to its original
value after parsing.

When a DASD is found to be required for the rootfs we should
be printing out a 'rd.dasd' commandline parameter. This not
only enables us to correctly enable the device with cio_ignore,
we can also inspect the resulting initrd to figure out which
devices are required to mount the rootfs.

There were some errors when rd.dasd parsing, resulting in the
device never to be activated. And we should check for
cio_ignore even if a udev rules has been found.
