I recently worked on the following RC bugs:
#691125 — ejabberd: package installation creates /root/.erlang.cookie
I tracked down the cause of this and provided a patch. Now I also know how piuparts works in detail :-).
#691180 — connman: Connman won't run due to missing libxtables.so.7
Since this bug does not affect testing and it doesn’t look like iptables 18.104.22.168-1 (a new upstream release) will go into wheezy (no freeze unblock filed), I tagged this with wheezy-ignore. I hope this was right, if not, feel free to correct me.
#684645 — liblockfile1: Order of fcntl and dotlock in maillock
I identified the piece of code which does locking the wrong way. Since I’m not familiar enough with either sendmail or NFS-safe locking, I did not send a patch. In case you have experience with this, please have a look!
