Bear with this question, but... I often find myself doing "yum install <some group>" and messing around with that a bit. Then I typically find that I only really want 1/2 the group or something. With the metapkg installed, won't I have to yum remove that in order to remove any individual packages from in that group? If so, will yum go into a depsolving erasure spree and try to remove the whole group instead of just the package or two I listed? josh -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
