So this is near-atomic, not atomic. More importantly, however, is the fact that dpkg won't know anything about this change, so will be unable to detect file conflicts between /usr/bin and /usr/sbin. And we know we definitely *do* have such file conflicts in the archive (see "node-like file conflicts"). Thus we could not guarantee the integrity of the user's system when making such a change. I don't see any gain from merging bin+sbin that justifies such pain. Adding sbin to the default PATH would be far simpler. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
