I don't see what a USE flag gets us: 1. If you have a separate /usr then either booting without an initramfs will work or it won't work - largely depending on how complex your environment is. Booting with an initramfs will work reliably (well, if we sort out the initramfs situation - having done some more tests I have one virtual machine which was pretty easy to get running, and one physical box that for whatever reason wouldn't detect/start the RAID). 2. If you don't have a separate /usr than booting will always work regardless of where the files are, since the system will always find them. Unless what is being proposed is to actually do the Fedora thing and make /bin, /lib, etc a symlink into /usr/bin, /usr/lib, etc than there isn't anything at package-install time for the flag to affect. If we do want to do the Fedora thing would a flag even work, since those directories get created from the stage3? It seems to me that if you want the symlinks you just need to set them up when doing the install (or from a rescue disk), and then the package manager should follow the links when doing subsequent installs. Oh, and not all package managers like the top-level directories to be symlinks. I think that as was the case with the use of bash vs sh we may need to have a policy decision made here. Right now the general policy has been to conform to FHS, and the Fedora/etc proposal does not do this (and apparently we are already a bit out of compliance). I think that moving in a different direction is a big decision. And, if we do decide to move in that direction, I agree with Samuli that we need a transition plan. Packages can't just start breaking initrd-less setups left and right overnight. To start, we need to get dracut/etc configurable to mount any necessary directories (I checked - it is fairly smart (though not 100% effective) at finding root, but does not try to mount anything else). Then we need to update our documentation. Then we need to communicate the change to users, and give them time to migrate. Only then can packages have the freedom to require usr to be available at boot. I don't propose that if we move in this direction that we "fix" anything that isn't currently FHS-compliant - the damage is already done. We just should avoid propagating the situation until users are ready. Rich
