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

live can be used also as an installer or rescue.
For altinst and rescue is nothing changes.

This is an alternative for 80rescue.cfg

These configs were used to generate grub menu items. This has not
been used for many years.

Thus lowmem will default for all items menu.

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...

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.

Instead of showing a warning, it is better to explicitly specify
the SYSLINUX_UI=none option in the config.

check conditions of  make  for equality of variables with an empty value
instead of check definition.
A defined but empty variable under all these conditions results errors.

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

With this change, we simplify the created initrd image. Kernel
modules and firmware are added by make-Initrd itself. The layer
in Initrd is now one. It also allows you to unifyed configs for
bootloading with propagator and bootchain.
Config files for refind and elilo is creates in mkimage, so have
to copy initrd.img in efi/boot/ with the name full.cz.

isolinux.cfg required for alterator-netinst.

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.

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.

For use them separately.

memtest is not part of syslinux.
Also replace tabs to spacebar.

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.

Directory syslinux can exist if using memtest feature.

Example:
@$(call set,SYSLINUX_DEFAULT,harddisk)
@$(call xport,SYSLINUX_DEFAULT)

60 seconds should be enough for any hardware.
It is important not to forget that the timeout for grub is measured
in seconds, and for syslinux in deciseconds.

Do not create syslinux.cfg if EFI_BOOTLOADER is set to not equal grub-efi.
