I'm not complaining, since I'm not one of your developers, and therefore
do not have to eat your dog food unless I choose to.

How odd, when the "hardware" in question is completely virtualized, and,
whenever it did occur, it would occur simultaneously in two parallel,
but physically distinct and independent virtualization environments,
both of which emulate completely different hardware, and use distinct
virtual-disk formats.

In fairness, though, this has not happened in quite a while now. I'm
only reminded because it surface for me again today, although the system
was nice enough to recover itself gracefully (on previous occasions,
dpkg --configure -a sufficed):

E: Sub-process /usr/bin/dpkg received a segmentation fault.
A package failed to install.  Trying to recover:
Processing triggers for initramfs-tools ...

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.
