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

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.

Such a menu may not be necessary.
For example, when there is no live.
Request by jqt4.

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.

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.

For use them separately.

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.

This reverts commit 5848ae70.

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.

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.

Simply Linux has a specific directory name with a theme.

Added for EFI only (see stage1/scripts.d/01-grub).

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.

Should be a (slightly cleaner) no-op.

...instead of hardwired 0x314 (which is rather wrong
for modern kernels and hardware, just ran into that
with yet another Matrox G200eW WPCM450).

This one is just like STAGE2_BOOTARGS but for rescue images
(which don't do that one for quite a few reasons).

There's a convention that syslinux configuration snippets
carrying the names of subprofiles involved are picked up
automatically; there were a few special cases already
when this is actually inconvenient, and there's another
one at hand so let's just step up and do it.

NB: this is a sort of a hacky hook though, wish an elegant
    interface would come to mind some day.

The issue is that gfxboot's gettext support works on "label"
strings but doesn't work properly on "menu label" ones as of 4.04
(the "menu label" translations pop up in the "Loading ..." window
but menu items themselves are unaffected thus untranslated).

NB: debian wheezy's syslinux-4.05 package patchset contains
somewhat related 07-gfxboot-menu-label.patch; might be worth
attention given that debian folks participate in upstream.

Its immediate purpose was influencing the GRUB boot menu
*but* the implemented mechanism is actually a part of the
long planned text branding and might be further merged
into branding when hierarchical features finally chime in.

So let's get the naming straight before it breeds.

File contents should be correct.
