Comment 5 for bug 340071

Sorry for misinforming you all. My fault.
Now the problem seems to be fixed in Ubuntu package management scripts. The directory location is checked and fixed when needed.
Earlier, there were some mess with resolvconf keeping its mutable state in /etc and requiring /etc (/) to be mounted rw too early in the boot process. Or may be this was just a legacy from my Debian unstable which I updated to Ubuntu 7.10 (or 8.04?) at some point.
