Please provide the full and complete list of all code on all Gentoo systems that are required in all supported configurations to support that end. Keep in mind you are dealing with an open-ended problem. Then provide patches to all ebuilds that will move said code to / Then provide a means by which any new code in the future can be detected to fall into this same category and alert the develops before too much breakage happens. Those three sentences above are not facetious. That is exactly what you are expecting the Gentoo maintainers to do. I don't think you grasp the full extent of this problem on modern Linux systems, it is not just a case of doing what you have to do to mount all other filesystems, it's a case of finding everything the must happen to do that and enforcing that none of it creeps into /usr. Which includes all manner of things users might validly want to so, most of it that you and I have never thought of. Recall how Unix treats everything as a file and lets you pipe, tee and redirect data in wonderful ways to produce output not envisaged by tool designers? The start-up sequence on modern Linuxes is starting to lean heavily in an analogous direction. The simple days of 1982 when everything in early boot was predictable are long gone. -- Alan McKinnon alan.mckinnon@gmail.com
