It is pulled by use/oem/distro target.

No star on e2k and armh.

lxde does not work on Sisyphus.

You must use the GNU MAKE variable, not a shell variable, and must
pass the REPORT variable to reports.mk.

NO_SYMLINK disables the creation of symlinks for the builded image.

make distclean should be launched after copying the log when
debugging is enabled.

fix commit e00c4243 regression.

efi=runtime enabled efivarfs suppot for realtime kernel.
But enabling this option results in high latency system response
that is unacceptable for real-time.
However, the system can still be installed by selecting
'EFI (removable)'. Secure boot has been supported since
December 2020 for this grub-efi bootloader installation option.

Use instead ve/alt-p9-ovz-generic.

.fop.xconf needed for building pdf.

The BRANCH parameter indicates that the target is a starterkit and
not a regular build for Sisyphus.

std-def is the default for the architectures on which it is available.

There are no more problems with firefox esr on aarch64.
This reverts commit 98f0735c.

Add multiple kernels support and initrd.img support instead full.cz.

Now you need to use engineering-install to install

- fix VM_SAVE_TARBALL parameter support
- grub: save ang read default menu item (thanks jqt4@, sin@)

1. Didn't work before because the variable was not exported.
2. Fixed the logic broken by the introduction of support for saving
the selected item on the FAT partition.

The code is given in accordance with the documentation
See-also: commit 2987fa8f

If the ISO image has a FAT partition and the image is written
to a flash drive, then it is possible to write to this partition
of the flash drive.
This is necessary, for example, if the user
does not want to install the system, but wants to constantly work
in LiveCD mode with or without recording sessions.
In order for this code to work, you need to make changes
to the FAT partition of the image on the flash drive:
Add the 1st line to the grub.cfg file:
set pfxfat=${prefix}
Write a 1kb file grubenv.
If grub.cfg contains a line like '^default=id',
then the read value is not used.

This prepares the ability to write and read
the default menu item from the grubenv file.
If grub.cfg contains a line like '^default=id',
then the read value is not used.
Setting the default menu item from the grubenv file
will be indented inside the 'if' optator and therefore
does not match the '^default' pattern.
