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.
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.
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
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?
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.
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...
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...
This one starts up a Firefox session in kiosk mode
(there are several extensions, I find hsv@'s one
preferable) and tries to browse /image/index.html
which corresponds to index.html in the image root
(could be edited by means of e.g. isomaster).
It's rather unexpected that someone would do an X11 LiveCD
without user autologin -- but even if that's the case,
then this waypoint is just not used for it.
Courtesy of prividen@, there's actual x86_64 client support in ALTSP.
Although led@ tells that it's i586 optimization that hurts on i686+
and should be replaced with either i486 or i686 for that matter...
A larger block size was recommended by led@;
gns@ seems to concur as the 512k value was borrowed
from liveflash.eeepc profile (along with -noI).
The other issue is with binary specific compressors:
x86 was clearly assumed while the data for an educated
guess are pretty handy. Please note that using filters
incurs additional compression attempts for the utility
to choose the best result.
There was a somewhat subtle Makefile->main.mk rename leftover
lurking in "everything" target: the default Makefile got used,
not the supposed main.mk -- which resulted in an attempt to
get way too much job done (the number of builds per target
became $ARCH squared, not just $ARCH).
Huge thanks to led@ for being an inspiring pedantic!
A minimal chroot supporting extension via apt-get;
vitals if built on Sisyphus as of Jan 16, 2012:
i586: 13M tar.xz, 58M chroot (33M w/o /usr/share/{doc,locale,man})
x86_64: 14M tar.xz, 60M chroot (35M w/o /usr/share/{doc,locale,man})
Trivial fixups (extra checks) added to two script hooks.
