In no way am I suggesting to EVER support ANY installation method that goes beyond what is already supposed to be allowed in bootstrap.sh and conservative CFLAGS. Portage cannot easily enforce limits on what users choose, and it shouldn't, it is a package manager not a system maintenance tool. You can, however, test, duplicate, and guarantee results using methods such as bootstrap.sh, which can easily enforce limits and account for circular dependencies. If you can do it from the command line, you can do it in a simple script. The bootstrap script _does_ work now, in spite of the openssl/python-fcksum circular dependencies a few months ago. Portage needed fixing, not the entire installation method. > The problem with a stage1 as *I* see it, is it that it's a grab-bag > system.

If you can't get it up from a bootstrap position, you merely mask the real problems and put off dealing with them until later, in a much crazier environment. If you can consistently obtain a working bootstrap environment for portage, no use flag _should_ matter afterwards. The same use flag will break a stage3, stage4, or stage99090 install. emerge -e system should work, every time, from a known baseline position. If it does not, something is broke. > There is no way around this, in my reckoning, without giving the user a > complete system to start with.

Hence you mask the real problem, which will come back and bite you in the ass again later. Eventually they will need to switch over to a new profile, perform a library incompatible gcc/glibc upgrade, etc... I have a hunch that judicious use of the build/bootstrap flags might be able to get around most circular dependencies. I don't know portage well enough to determine that. -- gentoo-dev@gentoo.org mailing list
