Bug#810785: ifupdown breaks debootstrap of Debian

[Raphaël Hertzog]

Package: ifupdown
Version: 0.8.5
Severity: critical
Justification: breaks the whole system
User: devel at kali.org

debootstrap of stretch currently fails due to ifupdown:
$ sudo debootstrap --components=main,contrib,non-free stretch stretch http://ftp.debian.org/debian
[...]
I: Unpacking libxapian22v5...
W: Failure while installing base packages.  This will be re-attempted up
to five times.
W: See /home/rhertzog/tmp/stretch/debootstrap/debootstrap.log for details
(possibly the package /var/cache/apt/archives/ifupdown_0.8.6_amd64.deb is
at fault)

debootstrap.log contains this:

dpkg: regarding .../ifupdown_0.8.6_amd64.deb containing ifupdown:
 ifupdown breaks systemd (<< 228-3~)
  systemd (version 228-2+b1) is present and triggered.

dpkg: error processing archive /var/cache/apt/archives/ifupdown_0.8.6_amd64.deb (--unpack):
 installing ifupdown would break systemd, and
 deconfiguration is not permitted (--auto-deconfigure might help)



The problem is that stretch still has systemd 228-2 and 228-4 is unlikely
to migrate quickly since it just got updated and seems to have a new RC bug.

I'm not sure what's the best way forward... possibly upload something to
testing-proposed-updates to drop that breaks temporarily until the package
migrates (and ensure 0.8.7 does not migrate before systemd).

Or force migrate the new systemd despite the age and the bug...

Ccing release team and systemd maintainers to have their opinion.
