Not necessarily. I chose the "empty directories must be tracked" wording to avoid that. If the PM were about to remove a directory that wasn't in the database of empty directories, then it could proceed normally. > What problem are you trying to solve?

If you're asking what problem I was trying to solve by leaving the implementation up to the PM, then I was only trying not to be pushy. If the "automatic keepdir" idea... > * Have portage call its keepdir code on any empty directories in $D > between src_install and pkg_preinst. is workable and if the PM authors are fine with it, then we could spec that.
