It is necessary so that the build session with screen is not aborted when the
ssh connection is broken.

But an open firmware opens an avenue for doing a wide variety of things, some of which are not necessarily related to telephony at all. Indeed, some applications may not even be useful, and only serve as an illustration of what can be achieved when running open source software. One such example is running Doom on the modem, because, ya’ know, everything needs to run Doom. Biktor put together a special (pre)release of the firmware which bundles X11, a VNC server and Chocolate Doom for those of you who wish to try this out. Below you’ll find a short video showing Doom running on the PinePhone’s modem.

For systemd not needed livecd-qemu-arch. systemd-binfmt.service makes
all the work.

At the moment it seems useless on other architectures.

It does not need to be set to std-def, if it is available, then it
is already by default.

This looks like missing in server starterkit for me;
builder one can be installed by hand if one knows how
to do that but let's better be explicit about that.

It's strange but ve/builder and distro/live-builder
along with distro/regular-builder are all mostly
"independent", that is duplicating functionality
without any reasonable gain; spotted finally.

See http://altlinux.org/gear/remotes for rationale.

It feels like time to introduce regular-builder.iso,
let's help it by factoring most of the common part out
into the feature.

...instead of setting up pam_mktemp ourselves
even if that was no big deal too.

su wasn't making it into the image breaking ~/.git setup,
and there's no reason for a full default boot timeout either.

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.

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...

If you make distro/live-builder.iso, the result is an image
containing almost everything (short of actual full enough
repository) to rebuild itself.  It will attempt to configure
eth0 with DHCP and reach http://ftp.altlinux.org for packages.

RAM requirements start with 2Gb, self-build is accomplished
on a 4Gb host with "make CLEAN=1 distro/live-builder.iso".

Packages required for "make distro/syslinux.iso" get included.

(some due fixups all over the place too)
