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

For riscv64 available grub-efi.
Needed added support for mkimage (mki-copy-efiboot-chrooted).

Not needed for other architectures.

syslinux is temporarily broken.

More than one BOOTLOADER may be available for the same architecture.
Set IMAGE_PACKTYPE in boot/iso, there is no point in duplicating
in different features.
Closes ALT bug 39786.

There is no point in duplicating conditions.

- Set BOOT_TYPE, BOOTLOADER to efiboot for aarch64 (needed mkimage 1.38)
- 'Simply Linux 9.1 (beta)' commits contained (Thanks sem@)
- mipsel-bfk3: Switch to 5.4 kernel, other changes (Thanks iv@)
- oem: Add use/oem/distro
- uboot: Drop BOOTARGS cma=192M
- net: Added switch between NetworkManager (etcnet) and NetworkManager (native)
  Assigned by default NetworkManager (etcnet)
- x11: Not add use/drm to use/x11
- efi: Add check EFIVAR_FS option
- sound/base: Add test-audio
- armh-mcom02: set screen resolution 1366x768
- realtime.mk: Refactoring, drop live with session support
- engineering.mk: Switch to MATE
- x11: Reduce size of kde5
- regular-vm.mk: Set as default un-def kernel flavour, drop lts kernel flavour

Reason: un-def supports booting on RPi4.
lts kernel flavour has not been updated for a long time.

firefox-esr crashes when launched on these architectures (Raspberry Pi 3 only).

With kde5-maxi image is too large (over 2 GB).

live with session support needed efi=runtime for cmdline kernel.
This parameter makes it unsuitable for real-time.

The std-def kernel is already set as the default in use/kernel for
the architectures where it is available.

make-initrd-propagator >= 0.44-alt1 always create alt-live-storage.

Removed from Sisyphus.

This script is not needed, since the identical script
features.in/plymouth/rootfs/image-scripts.d/10-plymouth is run
for stage2.
