Yes. I think it is also mentioned in the gentoo handbook. In fact, you should not use --unmerge because it doesn't check dependencies before removing the package. If you want to delete a package only if no other package depends on it, either remove it from world or use `emerge -av --depclean <package_name>`. The latter has the advantage of also telling you what depends on it. Regards, Florian Philipp
