Re: debootstrap and debian-ports

There’s another problem: even in the main Debian archive, “unstable”
is *not* guaranteed to be debootstrap’able, and has regularily been
broken.

Good news for m68k though: eglibc, gcc-4.8 and linux are no longer
in “unreleased”. In fact:

tg@freewrt:~ $ u=/var/lib/apt/lists/ftp.de.debian.org_debian-ports_dists_unreleased_main_binary-m68k_Packages
tg@freewrt:~ $ # test idempotency
tg@freewrt:~ $ grep-dctrl -r -P . <$u | diff -u - $u | wc
      0       0       0
tg@freewrt:~ $ # get me all source packages that have packages in unreleased/m68k
tg@freewrt:~ $ grep-dctrl -r -P . -n -s Source:Package <$u | sort -u
atari-bootstrap
atari-fdisk
gcc-4.6
gcj-4.6
glib-networking
gnat-4.6
google-gadgets
libbluray
m68k-vme-tftplilo
m68kboot
mesa
mysql-5.1
vmelilo
webkit

We can group them by:

• architecture-specific packages
	atari-bootstrap
	atari-fdisk
	m68k-vme-tftplilo
	m68kboot
	vmelilo

• architecture-specific patches, packages going away in sid soon anyway
	gcc-4.6
	gcj-4.6
	gnat-4.6
	mysql-5.1		(actually already gone)

• maintainer refuses integrating our patches
	libbluray		(maybe ping again?)
	mesa			(refusal also upstream)

• patches need to be updated against current versions of the packages
	google-gadgets		(waits on webkit/gtk)
	webkit

• “Build without libproxy, for bootstrapping.”
	glib-networking


None of them is, however, strictly needed for debootstrap
(although the architecture-specific packages may be needed
when d-i’ing a system). I read somewhere that Aurélien
regularily creates snapshots of debian-ports – which means
that we can install m68k from these, Right Now™.

deb http://ftp.debian-ports.org/debian-snapshot/2013-12-12/ unstable main

This should work. Maybe Aurélien can “freeze” one of these,
if needed?


------------------------------------------------------------------

Back to debootstrap. Yes, it needs support for multiple versions
(already has some, atm) and the unreleased distribution right now.

I guess APT’s ordering (from a given package, always use the
dpkg-numerically largest version, ignoring all dpkg-numerically
smaller versions, period) would work for now, as we don’t have
the arch:all/arch:any mix in the minbase, base or buildd set
much (except libsemanage-common). Everything else needs a very
complicated solver (such as, use an older libsemanage-common
that works with the libsemanage1 version in the archive) and
is out of scope for the sh-based debootstrap.
