OK so my working hypothesis is this. On Lucid /var/cache/bind is created simply by virtue of it being a directory within the package (see the bind9.list file). The group write permission is added by the postinst. If the Lucid package was installed, then removed, then installed again, the following

That is sadly not an option. LTS-backport kernel has a spectacular and easy to repeat Oops when namespaces are used. See #843892. It is not guaranteed by the kernel (it certainly wasn't in 2.6.32) that namespaces would be created and deleted instantly and without undue system pressure. It seems to
