If that doesn't expose the "specific file hierarchy" then I wonder what could ever qualify? Also eselect profile is a tool for convenience only, and nobody is forced to use it. The make.profile symlink and its target are mentioned in our documentation and users can set it manually. > The fact that some of our users like to poke around the internals of > the package manager doesn't change the fact that it has interfaces > that don't require direct modification. Hopefully we will keep having such users who want to understand the inner workings, instead of being satisfied with a black box. :) Ebuild repositories are human readable text, and we shouldn't move them to a hidden location. >> The same is true for license information in >> /usr/portage/licenses. > You have a fair point there.

I totally disagree here. We keep local copies of licenses for good reasons, and storing them on our webserver is no substitute. >> This follows the existing usage in eselect-repositories.

No, the argument is that we already use /var/db/pkg, and grouping other related things with it seems natural. > If you want to appeal to what BSD is doing then /usr/portage belongs > right where it is today.

As I said before, the two important parts are the move from /usr to /var, and that distfiles and packages are moved out of the repository. Apart from this (quoting the devmanual): "Gentoo does not consider the Filesystem Hierarchy Standard to be an authoritative standard, although much of our policy coincides with it." And the discussion so far has shown that the FHS wasn't designed for our use case. We can still use it as a guideline, but maybe we shouldn't jump through hoops, only to make it completely fit. > What other linux distro even has /var/db at all? Many (most?) of those that build from source. Also, Gentoo is not only a Linux distro. >> /usr/portage/packages -> /var/db/binpkgs > Why not put this in /var/cache? It is completely reproducible and > exists to save build time. That's what a cache is. *shrug* I don't have a strong opinion about this. To me, binpkgs look less cache-like than distfiles, but more cache-like than ebuild repositories. So /var/cache/binpkgs would work for me as well. The only thing that seems certain is that regardless of what we will do, we cannot make everybody happy. We shouldn't take that as an excuse to do nothing, because /usr/portage is no good solution either. Ulrich
