Something seems to have gone wrong with my bind installation. There was an upgrade to this: Version: 1:9.7.3.dfsg-1~squeeze10 when the upgrade ran, the owner on /etc/bind/rndc.key got changed to bind:bind. The service can't start until I change it to root:bind, as discussed in Debian Bug 386791. However the package then sits at partially installed (because it couldn't start). Any time I try to install other software, this post-install script runs, changes the ownership on rndc.key again, and bind fails to start. I've tried tinkering with what I think is the postinstall script: /var/lib/dpkg/info/bind9.postinst but I can't much debug output. and it seems if I try to install the latest bind with dpkg, my edited version of that script gets overwritten. What is the right approach to solving this? Regards, Andrew.
