any more to say on this? i guess i'll leave startprefix with me for now.

[snip] here's the changes i'm waiting to commit right now: A app-portage/prefix-chain-setup A app-portage/prefix-chain-setup/files A app-portage/prefix-chain-setup/files/ A app-portage/prefix-chain-setup/Manifest A app-portage/prefix-chain-setup/prefix-chain-setup-0.2.ebuild D sys-apps/portage/files/portage- D sys-apps/portage/files/portage- D sys-apps/portage/files/portage- A sys-apps/portage/files/portage- M sys-apps/portage/Manifest M sys-apps/portage/portage- A sys-apps/baselayout-prefix/files/baselayout-1.12.5-prefix-chaining.patch M sys-apps/baselayout-prefix/Manifest D sys-apps/baselayout-prefix/baselayout-prefix-1.12.5-r5.ebuild A + sys-apps/baselayout-prefix/baselayout-prefix-1.12.5-r6.ebuild A sys-apps/prefix-chain-utils A sys-apps/prefix-chain-utils/files A sys-apps/prefix-chain-utils/files/ A sys-apps/prefix-chain-utils/files/ A sys-apps/prefix-chain-utils/Manifest A sys-apps/prefix-chain-utils/prefix-chain-utils-0.2.ebuild i version bumped baselayout, although i guess it would not be strictly neccessary - just to be safe. there are two new packages - app-portage/prefix-chain-setup provides the prefix-chain-setup script, which is used to bootstrap chained eprefixes. sys-apps/prefix-chain-utils contains startprefix, and a toolchain wrapper making it possible to use the native toolchain of another prefix with chaining (making paths of all prefixes in play appear on the command line - this may be slow where exec is slow, and the chain is long - i can live with that). i attached a complete diff (without manifests) FYI, if you like to glance over it again - or just the parts you haven't seen. (i'll start writing changelog right now, so those are not there... :)) Cheers, Markus
