79d0208841 syslinux: added RESCUE_BOOTARGS support
This one is just like STAGE2_BOOTARGS but for rescue images
(which don't do that one for quite a few reasons).

1345c6e041 syslinux: dropped netinstall snippet (useless)
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).

18dbadd81c syslinux: introduce SYSLINUX_DIRECT
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.

54d19238ac syslinux: added 84rescue_remote.cfg
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.

07933f3c60 syslinux: mediacheck should honour bootargs too
...just like any other stage2 based boot target,

3e1fe68a54 syslinux: update rw to use cdrom method, not disk
The former approach to handling "LiveCD with sessions"
has been to mangle "automatic=method:cdrom" into
"automatic=method:disk,label:ALT*" within gfxboot
so that propagator and make-initrd-propagator would
try and discover/create a filesystem labelled
"alt-live-storage" on a LiveFlash's free space.

Then "live_rw" handling has been unified in
make-initrd-propagator (as of 0.18-alt1) to accept
any of "label" subparameter or "live_rw" argument
to go and create_disk_slice().

Then propagator's cdrom.c has been fixed to actually
try sdX1 before sdX (as of 20150306-alt1).

And now it's all been tested to verify that:
- flash "ro" and "rw" boot is OK
- CD-ROM "ro" boot is OK
- CD-ROM "rw" boot is fine given that there's
  a partition labeled "alt-live-storage" elsewhere

This is a can of worms indeed :-/

1a7eed303d pid1: initial "run as PID 1" feature
This one has been inspired by these guys:

  http://www.informatimago.com/linux/emacs-on-user-mode-linux.html
  https://raymii.org/s/blog/Vim_as_PID_1_Boot_to_Vim.html

It's aimed at building images running their main userspace
piece instead of ramdisk's init, that means PID=1, UID=0.

Mostly fun of course but it suddenly became interesting with
kernel IP autoconfiguration and e.g. elinks running this way
(NB: requires patched make-initrd 0.8.8 at the moment to get
resolver configured).

And startup times are way better than sysvinit and systemd combined!

ab84d06028 syslinux: "cdrom" notice
cfg.in/README should be explicit regarding
"automatic=method:cdrom" being usable for
flash media too (propagator has been fixed
since 20101130-alt10 or so, and gfxboot is
able to tweak the cmdline having figured
out it's running off the flash either).

bb37e68588 syslinux: slightly better mediachk label
It's not neccessarily installation media.

but still boot into rescue by default.

a2fcc601c9 syslinux: process @rescue_hash@ (forensic mode)
This value is used to authenticate rescue rootfs image
by verifying the squashfs file's sha256sum before use
(propagator-20140419+).

Looks like this check might be useful for other stage2
images as well but let's get started with this one.

Thanks Maxim Suhanov <suhanov/group-ib.ru> for both
http://www.forensicswiki.org/wiki/Forensic_Live_CD_issues
and propagator patches.

84a591471c syslinux: fix "forensic" wording
Thanks Maxim Suhanov (suhanov <AT> group-ib.ru,
http://www.forensicswiki.org/wiki/User:.FUF)
for taking the time to review regular-rescue image.

Note that there are more than just filesystems:
arrays, logical volumes and swaps aren't activated either;
startup-rescue >= 0.18 should make that clear enough.

syslinux shortcut handling is case-insensitive,
let's find yet another letter...

8362a7b905 syslinux: add forensics mode

ed75be87a1 syslinux: fix mediacheck label for gfxboot
Whoops, the very first build of a real distro with gfxboot
has shown that the label isn't picked up there... and things
are actually worse: iso.needscheck gfxboot test seems to look
up "check=1" in sectors where it might have been landing back
then but it's just not there by now; some kludgery is due in
branding-altlinux-sisyphus unfortunately.

3f547e2504 documentation: use paths relative to toplevel dir
This change is done to reduce ambiguity in some cases;
the previous intention has been to ease navigation when
staying in a particular directory, now it's been changed
in favour of convenient toplevel `git grep' in fact.

Both variants have their pros and cons, I just find myself
leaning to this one by now hence the commit.  Feel free to
provide constructive criticism :)

Some path-related bitrot has also been fixed while at that.

5f68010ae8 syslinux: add 40lateboot.cfg (_after_ ??live*.cfg)
Actually a copy of 10localboot.cfg with a different name
and sorting order so as to address #26608: there's no possibility
to make a LiveCD image that would boot itself by default if localboot
has been configured in.

It's only a partial solution as it doesn't override 10localboot
in case it's there already but a step in that direction...

a0d0be1a71 syslinux: fixed live_rw configuration
The initial revision was brilliantly buggy: it is *so* apparent

c7dadfd899 syslinux: ensure "default" line is there
alterator-netinst currently relies on "default"
being specified explicitly; it's wrong and it should
cope with the first "label" clause as well but we're
better off being strict to this script, not that one.

This commit should be no-op regarding syslinux itself.

429ce58608 added live_rw support
There's a need for a separate boot target since
persistent storage is way slower than tmpfs indeed;
usbflash has a tendency for huge performance drops
given simultaneous writes in addition to reads which
are the bottleneck already.

make-initrd-propagator 0.18 introduced ext4 rw slice,
so the corresponding kernel module needs to be included
into stage1; see also #28289.

NB: not available on x86_64-efi (or hybrid GPT to be strict)
due to fragility of the hack being made: parted(8) panics
upon seeing that, and good ol' fdisk is unable to treat it.

NB: use/live/rw use/rescue/rx use/syslinux/ui/gfxboot
are unlikely to play very nice together due to the latter's
magic l10n: "session" label is taken by live_rw config snippet
and *is* translated in design-bootloader-source;
OTOH "rescue_session" is *not*.

c12f0c17bc syslinux: drop "menu label" for gfxboot
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.

9ff596db7f syslinux: lowered livecd boot priority
The reason is that the most interesting live images by now are
installable ones, and while configurable boot order is not there yet
the "classic" livecd images will require manual choice to boot.

Thanks sem@ for reminding of that FR (which is still open).

d5cf1ff3eb renamed menuitem-grub feature to relname
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.

b21353a00c complex subprofile delimiter changed ("/" -> "@")
That sub/stage2/install2 was somewhat clumsy actually as it looked
like a hierarchical thing while being a substitution thing:
generic stage2 would get put in place renamed as install2.

This could only get worse with hierarchical features which have
already been both requested and considered for quite a time,
and "stage2 at install2" reads much more naturally.

cbfc3db882 syslinux: honour META_VOL_SET for boot menu

will now offer to "Install Simply Linux".

46e3c94707 syslinux: no ui, no escape
This one was suggested by enp@ for industrial use where
some extra protection for the boot process might be quite
desirable.

If no syslinux ui was specified (the stock configuration paths
ensure there is one) or if it was set to "none" explicitly,
then there's no boot: prompt (let alone any menu).

If there's a need to ensure that the boot process is not
interruptable by Ctrl/Shift/Caps Lock/Scroll Lock.

cb764516eb build-vm: standalone build is a must, too
The problem was spotted by Alexander Bandura:
bin/tar2vm wasn't present in the generated profile.

I considered extending features.in/Makefile to include
bin/ alongside lib/ but that would make the helper's location
unpredictable (unless BUILDDIR is specified explicitly) so
restricting sudoers would be harder; worse yet, the copied file
would come with write access for the user building an image.

The implications in restricted case are complex enough anyways
so the recommended implementation would only include a fixed
readonly location like /usr/share/mkimage-profiles/bin/tar2vm
as laid out in doc/vm.txt, and that means it's in the metaprofile
not a generated profile.

8989fc2771 added plymouth feature
An initial draft of it was done half a year ago but several tricky
thingies had kept the code from showing up as it was rather brittle
and incomplete.

This implementation involves quite a few changes all over the place
but finally works good enough for live and installer images.

Please pay attention to the versions of these packages:
- installer-feature-setup-plymouth (0.3.2-alt1+)
- branding-altlinux-sisyphus (20110706-alt2+ if used)
- plymouth (0.8.3-alt20.git20110406+)

51f5b88062 initial branding feature

regard.  Hence the dedicated feature comes to the rescue
(well no, it doesn't actually mess with rescue!).

b5e6906b56 syslinux configuration revisited
- incompatible change (to fix the rather broken early style):
  use/syslinux/ui-% is now use/syslinux/ui/%;

- default timeout changed to 9 seconds (long enough and keeps
  the countdown in a single figure);

- added totaltimeout of 300 seconds;

- provided live kiosk images with almost-instant boot by default;

...and some other assorted tweaks here and there, sorry.

1b885b3d24 cleanup scripts rehashed
There's much reason for reuse instead of duplication
among the different stage2-based subprofiles.

In particular, the rather monolithic driver cleanup script
of the ancient is better done in several clear pieces with
the final depmod run.

Scripts dropping apt/rpm databases will dump pkglist first.

A script purging /boot/* will honour live-install if present.

Minor inno^Wfixups all over the map too.

ed7bf0db9f initial ISO9660 metadata support
As was noted by Alexey Shabalin in libosinfo context,
current ALT Linux images tend to lack ISO9660 metadata
-- which they did have back in the day of Master 2.4.

Please note that the data collection occurs this way
due to mkimage's config.mk resetting the values to be
empty; this was worked around by using another config
file, $(BUILDDIR)lib/iso.mk, and including it later
but that would require a separate target with per-target
CONFIG variable which isn't elegant at all given the need
to actually build up the metadata set.

So the variables were changed (to be more readable anyways)
and then proxied back to BOOT_*.  This might be cleaned up
some day after the inclusion order is tweaked or mkimage
defaults get set-if-unset-yet (?=).

180ed5359c "if test ..." replaced by "if [ ... ]"
Fixed up the remnants of the early style mix
to correspond to the proposed doc/style.txt;
the rationale being that

	if [ ... ]; then
		...
		...
	fi

is the more readable construct among itself,

	if test ...; then
		...
		...
	fi

and

	[ ... ] && {
		...
		...
	}

due to the condition being more distinguishable
when bracketed and the body more apparent as the
one inside "if" and not any other block; the less
obvious difference is that the final construct of
the latter form is prone to the whole script exit
status being non-zero if the condition isn't met.

dbed41bf81 syslinux: *.cfg tweaks
- parameter order fixed to "simple first, then those with args"
  and documented as the preferred one (might be debatable, okay)
- added "lowmem" to live so it avoids a ramdisk but works off media
  (it's a knob for propagator)
- added "fastboot" everywhere (but failsafe install) to make use
  of Linux 2.6.29+ async controller initialization
- every snippet got a trailing newline so that isolinux.cfg is readable

And a fancy makefile to check for shortcut dups!

bc8251f3f8 features.in/syslinux: bump livecd boot priority

ad68750855 experimental server-ovz-netinst image
It's now possible to:
- make distro/server-ovz.iso;
- make distro/server-ovz-netinst.iso;
- publish the former image's contents on ftp.linux.kiev.ua;
- boot the latter (~17M) image and enjoy the netinstall ;-)

The catch is that the stage2 (altinst file) location has to be
hardwired into syslinux config snippet for things to happen
automatically -- even if it can be specified manually in case
of failure.

The other catch is that currently a netinstall image is somewhat
tied to the particular image it installs since stage1 kernel and
stage2 modules must correspond strictly (the typical symptoms of
the glitch would be missing mouse driver and weird "permission
denied" errors during an attempt to partition the hard drives).

It might be desirable to provide multi-distro netinstall image...

9cedefdba9 introduced add_feature function
The features might get copy-pasted (or even copied-and-pruned)
when initialized; there's an unneccessary duplication of the
function name in the line adding it to FEATURES list, thus
prone to being forgotten and causing some havoc later on.

It was wrong in the first place but tackling this with some
double-colon rules ran into terminality issues, and further
tortures were considered unneccessary.

The current solution isn't perfect (no completely transparent
function name registration upon corresponding target being called)
but at least it is an improvement...

Back then I didn't come up with anything smarter than
