I believe FreeBSD uses an INDEX file in /usr/ports/INDEX, and then compiles that file into a berkeley DB file or something in /usr/ports/INDEX.db. I'm not really very fond of FreeBSD ports these days, actually. It has the feel of something hackish, in desperate need of a good bottom-up redesign. I'm starting to think that Gentoo's Portage is superior in almost all ways, but I do think this search speed thing needs to be dealt with. I'm using esearch now, which is nice, but rebuilding the database is a royal pain in the rear, and the database isn't kept in sync between emerge runs. If the esearch database could be updated without having to rebuild the entire thing (or at least without having to look at the filesystem to rebuild the entire thing) after every emerge operation then I think we'd be doing well. -- Jesse Guardiani, Systems Administrator WingNET Internet Services, P.O.
