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.

Squash live is big.

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

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.

This is not required for grub >= 2.04.

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

At the moment, the ability to select the kernel with which to boot is
implemented only for grub (grub-pc, grub-efi, ieee1275boot).
note that renamed STAGE1_KFLAVOUR to STAGE1_KFLAVOURS, as multiple
kernels can now be added.

Needed for use one grub.cfg config for all grub platforms.

In menu you need the name of the distributiv.
If not set, then we will be as before.
Also corrected the selection of phrases for translation.

Pay attention to what you are adding to the variable. No need to
add language and live_rw there! Они нужны только для refind.

These changes allow you to create two independent config at the same
time or separately. It will be possible to add support for grub-pc in
the future.
