Hi Zac, I see Gentoo:Prefix users used to advise to place in /etc/portage/profile/package.provided e.g.: sys-libs/glibc This is not possible anymore, I need to specify a version and without leading '='. It is awkward, on a Prefix host I really want to avoid glibc, kmod, pciutils, etc. See http://how-to.wikia.com/wiki/How_to_install_Gentoo_emerge_on_a_non-Gentoo_Distribution_of_Linux Thank you #

i'm not sure package.provided ever allowed unversioned atoms. it's needed because packages will do things like ">=sys-apps/kmod-20" and portage has to know what version you've provided an equivalent for. conversely, if you provided a new version, but a package wants an older, portage needs to compare that too. i suspect it's difficult in the depresolver to inject a new type that will behave correctly in all cases. for example, if a package had a blocker against an old version, presumably you wouldn't want it to get flagged (on the assumption you provided a newer one). but you would want it to block if no version was specified. seems easier to just force people to stick a version on there.

On a Gentoo:Prefix-ed installation, you want to avoid sys-libs/glibc altogether, likewise sys-apps/kmod, pciutils, etc. Possibly also many apps with SUID binaries because you cannot give away file perms, you cannot create the SUID bit, cannot even mount a filesystem as root, etc. In overall, updating the version numbers would be a boring task and truly a nightmare. Adding alt@ for eventual comments.

Adding alt@ for eventual comments. When you do have glibc in your Prefix, then you have the "Standalone Prefix" (having "~amd64" style keywords), which is the default choice on Linux. To omit glibc and similar from Prefix, you want the "Guest Prefix" instead (having "~amd64-linux" style keywords), which you get when PREFIX_DISABLE_RAP=yes environment variable is set during bootstrap, like: $ PREFIX_DISABLE_RAP=yes ./bootstrap-prefix.sh ...
