Hi,

Recently when working on a simple bug [1] I've run into a need to change rootwrap filters rules for a few commands. After sending fix to Gerrit [2] it turns out that when testing the upgraded cloud grenade haven't copied my updated volume.filters file, and therefore failed the check. I wonder how should I approach the issue:
1. Make grenade script for Cinder to copy the new file to upgraded cloud.
2. Divide the patch into two parts - at first add new rules, leaving the old ones there, then fix the bug and remove old rules.
3. ?

Any opinions?
