Since iproute2-2.6.35, ip is installed in /bin/ip and not in /sbin/ip anymore. Reproducible: Always
Whoever did the change, should have checked if pkgs in tree were referencing /sbin/ip or at least keep backward compatibility (symlinks).
@QA: maybe it's time to setup some rules for moving stuff around. Once again, unstable doesn't mean unusable.
iproute2-2.6.35 isnt in the tree. dont report bugs against outdated systems.
Funny, nothing is actually pulling in the fixed package here, how can you expect people to know that iproute2-2.6.35 was totalled?.
Patch to prevent this from happening was added in vzctl-3.0.24.2. Actually scripts should not use full path. It's administrator responsibility (or system scripts) to set it correctly.
