Doesn't work with grub 2.12. Show warning:
"vga=normal is deprecated. Use set gfxpayload=text before linux
command instead."

This parameter is used to configure the network in the initrd, but
we don't need it. startup-rescue 0.50 no longer requires this
parameter.
See https://bugzilla.altlinux.org/50526

This is an alternative for 80rescue.cfg

GRUB since 93a786a00 (kern/efi/sb: Enforce verification of font files)
has enforced verification of font files in secure boot mode. In order
to continue to be able to load some default fonts, they are added to
the built-in memdisk bundled with a signed EFI image and may be
accessed by file name prior the actual default path.

Thus lowmem will default for all items menu.

This variable was need for rEFInd (it no longer support). The
variable was added to grub menu, but was not in needed.
In server V, this has remained since rEFInd.

The new target adds rescue mode to the regular livecd.
live should do not be installable, since in it serious changes
that are unacceptable for a normal system.

This reverts commit 791bd8ab.
altinst is  big...

Squash live is big.

memtest86+ >= 6.20 there is only in Sisyphus yet.

Note: efi shell is not signed.

Note: memtest86 is not signed.

This option is only for gfxboot on syslinux. It hides the options
to the left of it from the user.

The installer works more reliable when loaded to RAM.

This feature complements the live image of the second stage with installation
image-specific settings and scripted hooks.

It is recommended to connect using +live-installer to ensure that a typical set
of installer-related features is included.

Unlike the install2 feature, a separate image of the second stage of 'altinst'
is not built, but the live image is supplemented with installer packages in
order to reduce the total volume of the iso image.

Installation consists of two stages:
1. The live image is unpacked, as in livecd-install
2. Install additional packages BASE_PACKAGES and package groups THE_GROUPS as in install2.

Unlike install2, only those packages that are not in the live image are placed in the main repository. This is how the size of the iso image is reduced.

If do not specify ip=dhcp, bootchain network boot methods will not work.
Since make-initrd 1.33.0.

This is not required for grub >= 2.04.

Kazakh language is not supported in alterator-sysconfig.

The parameter 'nosplash' must come before the splash argument.

This will allow for ISO, writed on flash, disable gfxterm and
enable serial console, if necessary. For EFI only.

Example:
GRUB_TERMINAL='console serial'
GRUB_SERIAL_COMMAND='serial --unit=0 --speed=115200'

Not need to configure all network interfaces. propagator and bootchain
configure one network interface detected on network boot.

The 'splash=0' parameter not only disables splash, but also switches
to tty5 on which plymouth is supposed to run. This looks like a bug
in propagator. 'nosplash' is also a general parameter for propagator
and make-initrd.

This parameter needed for bootloading with initrd-bootchain.
there are currently no network configuration dialogs when booting
with initrd-bootchain.

For install2, this is needed to work around error 99-cdrom.sh with method:cdrom.
The error shows up with make-initrd-bootchain, but not propagator, as lowmem is
enabled for propagator in this mode.
For rescue, the point is that the latter has become quite large, so by default
it would be better that way.
