I almost wonder if we should consider adding a task which handles the
above in addition to the standard bitbake clean. I was burned a few
weeks ago by having a stale package in my deploy directory that kept
getting chosen over the new one I was building due to some versioning
nastiness. I can see how automatically purging stuff from deploy would
be considered destructive, but IMHO there should be a command which just
nukes every last bit of a package the build system knows about.
