Which would also be true for the daemon. Obviously it wouldn't be able to have permanent locks on the DB, but something with fam/imon/poll to watch for rpmdb changes, lock, update, unlock...would that be reasonable? > So what's nutty about using del.icio.us instead of rpmfind.net? I'm all for using tags as a replacement for Group: which went up a creek the moment other distros stopped giving two hoots about /usr/share/doc/rpm-4*/GROUPS. Are you also advocating using del.icio.us as an rpm search engine? I'm not sure how that would be better than updating rpmfind.net to use tags, as it is a niche engine where del.icio.us (which I'm *really* starting to hate typing, BTW :P) is all-purpose. A delicious search on "rpm" revealed that rpm is related to "music." Neato. :-) Michael -- Michael Jennings (a.k.a.
