Careful about removing /etc/rc?.d. I did apt-get upgrade last night and got an upgrade of hildon-desktop. The upgrade failed and I ended up having partially installed package. Too tired to investigate, I left it for the morning. To cut it short, the problem was that part of the post-inst process is updating the rc.d folders. Since I had them removed, this phase failed. I fixed it by recreating the folders (0 to 6 is enough, S is not used) and running apt-get upgrade again. I assume that fixing /usr/sbing/update-rc.d would have the same effect, but it is a bit late for me to try that now. Perhaps someone else can verify it works? The fix I had in mind was replacing exit 1 on line 141 with md "$etcd$1.d".
