That means you have no more than 15 characters for an inter= face name, so renaming the interface is also fraught, and also requires an additional check for conflicts after the rename. Which would also require correct lock handling (which is currently absent). This doesn't actually av= oid the problem it tries to avoid. --=20 You are receiving this mail because: You are the assignee for the bug.=
