QEMU for riscv virt machine passes its own DTB. Overriding DTB breaks
Linux loading.

ttySI0 was a name of HiFive Unleashed serial console. It was changed to
ttySIF0.

The intention behind this commit to allow user to get all needed stuff
to launch a particular image inside QEMU without need to download the
firmware from the net or in a case of booting procedure change in
future.

Education rescue does not require wireless support.

startup soon won't be installed by anyone.

isolinux supports Hardware Detection Tool.

As new exfat filesystem is merged into linux-5.7 kernel, exfatprogs is
created as an official userspace utilities that contain all of the standard
utilities for creating and fixing and debugging exfat filesystem in linux
system. fuse-exfat not needed.

This is necessary for kernels 5.10 and higher on systems with sysvinit,
since no one else on these systems except this service will mount
evivars in /sys/firmware/efi/efivars.

Also needed for livecd.

cmac.ko needed for use SMB2 and newer.

The base font is needed not only in the installer, but also in the
installed system, since the final steps start alterator from the
installed system.
use/fonts/system leave as an alias.

squashfs built with this option are not loaded with modern kernels.

Sorting profiles was a mistake. stage1 must run ahead of the stage2
subprofiles, as this is the stage where the squash compression
settings are configured.

List base+regular+extra contains lvm, mdadm, which are not needed
in rootfs.

So that you can not add them to rootfs.

In mkimage 0.2.41 it is implemented only for mki-pack-efionly-isoboot,
mki-pack-grubpc-isoboot, mki-pack-isoboot.

By default, when building an image, xorriso generates
an image UUID of the form YYYY-MM-DD-hh-mm-ss-cc
from the current time.
If the xorriso command line has a parameter
-volume_date uuid YYYYMMDDhhmmsscc
then the UUID of the image is generated from it.
This feature reads the current time and creates variables:
UUID_ISO containing YYYY-MM-DD-hh-mm-ss-cc
UUID_ISO_SHRT containing YYYYMMDDhhmmsscc
Also add 60-cdrom_id.rules to initrd
This allows to identify CD/DVD by UUID
and use to boot the installer
method:disk,uuid:YYYY-MM-DD-hh-mm-ss-cc
