15 My current development status on this is not much more than "proof of concept",
16 although i had to suspend the work on this project until ~Jan. 2006 due to
17 some decisions in the company i'm working in.
19 But what's already done:
21 I imported portage in my own cvs-repo as a vendor branch a few times,
22 but the last import was at 2005/05/24.
24 The SUPPORTS-variable comming out of the GLEP-Thread works, and it's already
25 possible to start an 'emerge system' on a non-Gentoo Linux (RH/AS 2.1), where
26 24 packages already merge successfully. I did also some auspicious tries on
27 Solaris 2.8.
29 To bootstrap the first prefixed portage instance, i've some similar (but very
30 reduced featured) package-building-system, which only needs a running posix-
31 shell, a GNU-make, some compiler to build binutils/gcc and some coreutils found
32 on every *nix. I use this one currently to compile the bunch of our own (mostly
33 closed-source) packages on HP-UX/AIX/SunOS/Linux/Cygwin,
34 but it lacks many useful features found in portage.
36 Once there's a running portage in some prefix, this one should be able to
37 bootstrap another portage instance in a different prefix.
39 For the ebuild-tree:
40 The one i use is a very reduced set of ebuilds initially based on a gentoo-tree
41 snapshot as of 20050626.
43 I've defined secondary profiles setting a USE-flag 'secondary' (unsure if really
44 needed), and made a new sys-apps/baselayout-secondary package providing a
45 /${AFFIX}etc/profile, which does not just _set_ but _extend_ path-style
46 env-variables when sourced. This required some additional portage extensions
47 to create an /${AFFIX}etc/env.conf to be used by this /${AFFIX}etc/profile.
