[Bug 807974] Re: debootstrap fails to install libc6 installing oneiric from natty

[dj_palindrome]

Excuse me if it is inappropriate to say this here, but a seemingly
related series of breaking changes still persists. First, X lost all
input devices. Then, there was a hang on boot. The Plymouth logo stopped
spinning and the system just croaked; the login screen never appeared.
The latest breaking change occurred while upgrading *one* package only
(base-files) to 6.4ubuntu2. Supposedly that was expressly intended to
fix other devastating bugs. After that, I gave up and reverted to a
stable snapshot.

I'm all for stealing from Debian Unstable, but when this is done in a
piecemeal and uncoordinated manner, and Oneiric is orders of magnitude
more unstable than Sid, something is wrong. Really, this is getting to
be too much. I'm not talking about an ugly screen or a few missing
icons. We are approaching total unusability.  More often than not, dpkg
receives a segfault during routine upgrades.

Bug description:
  When trying to create a minimal oneiric install from a natty release,
  I get this error:

  leonardo at debby: sudo debootstrap oneiric oneiric

  And it seems that /var/run is missing:

  root at debby:/# ls /var
  backups  cache	lib  local  log  mail  opt  spool  tmp

   If I "mkdir /var/run" then I am able to install
  libc6 and finish oneiric installation with dpkg.
