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 (?=).

openssh-server is in need indeed on almost any server instance;
thanks Aleksey Cheusov for reporting the shortage.

This might be amended in the future but is reasonable right now.

Mostly multiline compactions, but also use/install2/net
got factored out from distro/server-ovz for future reuse.

- reports (targets graph)

These are better off in their own lib/help.mk

As noted in doc/assumptions.txt, the SHELL based target tracing
only works for rules with recipes, even empty but present ones.

The simplest thing to do is hooking "; @:" onto the rule's tail
(one-liner with a non-printing shell builting "true" command).

The purpose is being able to examine particular target interdependency
graph for a given image having been configured to avoid convoluted
dependencies (loops in particular).

The implementation is based on SHELL hook hint by John Graham-Cumming:

It looks like the intermediate targets aren't all equal:
some define a finished feature while some create a common
lower level piece of configuration.

Let's do shortcuts for the former so that a distro line can be
more terse and descriptive; help targets in features.in/ tweaked
accordingly.

- distro tweaks

There are pseudo-distro targets that are useful to combine
the needed bits and pieces for a few more different end-user
images but that are useless themselves (e.g. desktop-base
wouldn't even start X session before someone would have
installed a window manager).

Let's just hide these under the hood so that `make help',
`make everything' and potential frontends don't bother.

A minimal live, tiny desktop system and a test LTSP installer;
all of these work.

The package list taken from mkimage-profiles-desktop
and trimmed down due to current TDE packaging difference
as well as extras being defined elsewhere.

ltsp-icewm used to be the only ALTSP (testbed) distro over here
but now its terminal server part works good enough to seperate
it from the UI part.

A few additions to facilitate testing, tweaking and benchmarking:
iftop, openssh-server, mplayer

ptbatterysystemtray is a bit annoying out-of-box,
should run only if battery found and should not
throw up a dialog upfront for no real reason.

If we have a supported display manager, we should rather autoconfigure
that one for autologin instead of configuring autologin package:
those tend to play better with "modern" session management in terms
of runlevel control etc.

xdm doesn't really differ though.

TODO: maybe skip autologin *package* configuration if any dm found
in the live image-script?

The main part is done as per
https://wiki.archlinux.org/index.php/LightDM#Enable_Autologin;
there's an issue that the lightdm developer insist that autologin
user belongs to "nopasswdlogin" group though.

alsamixer *is* useful :)

GPU firmware might have been missing otherwise...

(via a specially crafted pkglist name)

These are gone for now, this fix should have been done before.

- minor fixups

From what I've read so far, most of the code should run on 3.80;
there seem to have been some bits that are dependent on 3.81
features, but there is not a bit that depends on 3.82+ features
so far.

It's preferred for Razor-qt's logout app to be able to turn
the system off or reboot it; xdm lacks consolekit support.

Thanks Alexander Sokoloff for the hint.

The main package has been renamed from razorqt to razor-qt
to fit upstream brand better.

If there's an ethernet interface, a DHCP client, and these
can result in connectivity out-of-box, then it's rather
a feature for almost any LiveCD.

Thus the configuration script is moved from dev feature
to live one with the addition of dhcpcd/dhclient test.
This is asking for some more neat solution though...

alterator-ltsconf needs further testing,
and aplay is handy for remote audio tests.

As it happens, I've stumbled upon a successfully built image
with alterator-grub in BASE and lilo in install2's installer-steps.
Of course the installer bailed out after dealing with packages :-/

Thanks Leo-sp50 for pointing out the (hopefully) right direction.

There's still an annoying problem (a race?) manifesting itself
as installer bailing out between packages installation and lilo
setup with X segfault in logs; while the culprit is not known yet,
let's avoid that for most images by moving the bootloader request
from the former "leaf" target (which noe became a "node") into an
experimental server-systemd one.

Thanks Leo-sp50 for bringing that to my attention again; see also
http://forum.russ2.com/index.php?showtopic=3310&pid=31364&st=0&#entry31364

As was duly noted by Leo-sp50, both server.mk and desktop.mk
duplicate a few bits layered over bare distro/installer which
happened to be both a dependency (thus should reduce redundancy)
and a "real distro" target (well, it doesn't just work yet, need
to provide networking and sources.list in install2 by hand).

Fixed by moving a "node" to distro/.installer along with typical
additions and leaving a bare installer as is by now; there's a
need to get it working at least for DHCP/ftp.altlinux.org case.

From now on, non-empty SAVE_PROFILE variable will indicate
the need to carry the particular generated profile inside
the image built from it.

Thanks gns@ for this feature in liveflash.eeepc.

So far the tagged scripts concept is too fragile,
and these were used unconditionally anyways.

features.in/Makefile is broken regarding copying
tagged scripts right now...

Was broken during dot-base introduction
by wrong recipe split...

This is to fit base/extra separation better
and to avoid lvm2 creeping into VE images.

- live-related tweaks (including live.hooks support)
- terminal server and webkiosk images

xorg-drv-intel doesn't pull it in at the moment:
https://bugzilla.altlinux.org/25044

Rather convenient for native flash images but can also be
beneficial with usual ISO by editing one before burning it.
