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

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.

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

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.

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

I've just borrowed glebfm@'s one introduced by commit
ec23a8ec before; this
still might be improved it seems.

These happened to collide after initial copypaste
of 20install2.cfg snippet, spotted that recently.

This one enables rw session support for Rescue images;
the nitpick is that syslinux' gfxboot *will* set this up
when booting the same ISO from USB Flash media instead of
optical one (CD/DVD-ROM/RW), and we don't put gfxboot into
a standalone rescue image.

A one-liner for syslinux and a simple installer feature
change a lot in this regard!

Was broken in too many places including several libraries
x11vnc currently links against getting removed, several
utilities missing, and no way to guess what to do...

One could stumble upon http://altlinux.org/vncinst
or find the implementation in installer.git but it's
not exactly user-friendly.

Turns out it's "splash=0" that does the job.

...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 related to forensics mode handling in mkimage:
there's a regex that's expecting the old string ending with
hash value, and it stops working when this is changed here
(at least as of mkimage 0.2.18).

So partially undo the change for this particular file to avoid
refind's example menu for regular-rescue.iso (or any other image
involving forensics mode), and hope to revert this commit some day.

This keyword was misused due to the lack of understanding
of its meaning; thanks zerg@ for the hint, let's hide the
kernel boot parameters not expected to be modified by user
under the hood (and vice versa in some cases).

Note that this is just a keyword shift in all cases
but mediacheck where "showopts" is now added.

NB: this keyword is only relevant for gfxboot.

"Failsafe install" disabling APIC/LAPIC looks somewhat obsolete
by now; the only reasonable part seems to be the attempt to force
VESA videodriver for the installer (should be done within installer
itself though).

"Forensic mode" submenu has fallen apart after the original commit
as the tricky logic in mkimage::tools/mki-copy-efiboot failed to
pick up the new variant; this should all be redone (solo@ has
started doing something but it needs a time-consuming review).

Fixes: 79d02088

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

This one was an experimental but the server is long
offline and isn't going back up; remove the obsolete
config snippet, if/when it's done again it's the easiest
part to be restored (the implementation should provide
HTTP/FTP/NFS-publishable deliverables without the need
to extract those from ISO images).

This one provides cmdline arguments for startup-rescue >= 0.24
which would bring up networking and sshd in its turn thus allowing
remote access to the host booted in this mode.

The feature has been asked for by many people including mithraen@
and valintinr@ (and I'd make use of it another day too).

See the appropriate startup-rescue commit description for notes
on implementation; this default set of variable values should be
both useful and illustrative though.

...just like any other stage2 based boot target,
both for consistency and specifically for propagator
test image.
