The bootstrap and system install is dependent on ibiblio at this point for downloading of packages. Changing in make.globals doesn't help because it is overwritten at the start of the bootstrap by the base packages (not sure exactly where). Exporting the GENTOO_MIRRORS got me through the bootstrap by using hte French mirror however when emerging the system some packages failed because they still tried to pull from ibiblio. Ended up using URL rewriting in Apache to get to the french mirror (different path name some simple host redirect doesn't work). It would be desirable to include multiple mirrors that would be run through for all packages taking into account the different paths on different mirrors.
I think the way to do this is to upgrade ebuild.sh: 1. define GMIRROR=http://www.ibiblio.org/gentoo/distfiles 2. In the ebuild.sh download loop, redefine GMIRROR to point to the "current" mirror 3. Then ebuilds can have SRC_URI="${GMIRROR}/foo.tar.gz" (We can't use GENTOO_MIRRORS since it's designed to hold multiple mirrors; thus GMIRROR)
This is fixed in portage-1.8.9_pre14 (in testing). You can now specify SRC_URI="http://mirror/foo.tar.gz" for files that we mirror directly. "http://mirror" gets expanded to the first mirror defined in GENTOO_MIRRORS, or our main ibiblio source mirror if no GENTOO_MIRRORS are defined.
