To follow this up, the .deb at least on Lucid does NOT have the write
permission set.
amb@nimrod-ubuntu:~/bind-test$ dpkg -c bind9_9.7.0.dfsg.P1-1ubuntu0.8_amd64.deb
| fgrep cache
drwxr-xr-x root/root 0 2012-10-09 14:13 ./var/cache/
drwxr-xr-x root/root 0 2012-10-09 14:13 ./var/cache/bind/
I've tried this on a pristine Precise box and it doesn't go wrong because
Precise does not remove /var/cache/bind as it is populated (unlike on at least
some Lucid installs). However, if I manually remove the cache directory, it
does go wrong:
