USE flags used, and thereby dependencies are stored in the package, so when you use downloaded packages, they override your own USE flags.

I can understand some of the rational. from "man emerge" <quote> --usepkgonly (-K) Behaves just as --usepkg except that this will only emerge binary packages.

Seems a bit odd that it would force the -re- emerging of packages. I guess you'd need to have them around for dependency tracking though.

USE flags probably. as -puvg --deep world will use USE flags and therefore dependencies from the online packages, and not those calculated from your machine and its tree. > Why does -g download already merged dependancys? > Now this is getting on my nerves as I really don't have much room on > my laptop's disk.

Now this is is strange behaviour, I think it might be a safteyprecaution but I'm not sure at all. :/ > Is there any way to stop that? Is it a bug? File a bug , put it nicely and question it, I'm sure that if the portage devs don't have a good reason, they can change the behaviour. :) > Many thanks to any portage gurus responding ;) No guru, but I've worked with it a bit through chinstrap. //Spider -- begin .signature This is a .signature virus!
