Bug#767999: problem with debootstrap in wheezy

[Santiago Vila <sanvila@unex.es>]

Note: dpkg 1.17.21 has migrated to testing, and, as a result, the
current debootstrap in wheezy is now unable to create chroots for both
jessie and sid (previously it was only sid and jessie still worked).

As of today, in jessie we still have base-files 7.6.

So, as I suspected, the recent changes in dpkg are the most likely
reason why this problem didn't bite us before, not the changes I did
in base-files 7.7.

I hope this might definitely clarify some past misunderstandings about
this problem.

Thanks a lot.
