IIRC you did not manage to inform it where to download things from.
But it's ok for me to have a bootstrap-script in the tree, even i don't
plan to use it.


Well, here are the two portage patches for dynamically duping
environment values. Patch-Numbers fit into my previous mail containing a
bunch of other patches [1].

[06-env-conf+ext.patch]
Let portage create /etc/env.conf containing somewhat a dump of the
environment bits found in /etc/env.d/*, to be read by /sbin/extenv, see
below (the baselayout-prefix.ebuild).

[07-env-dup.patch]
Interpret variables PORTAGE_ENVDUP* found in /etc/env.d/*, to dupe
values from one environment variable to another. Example is to dupe
values from LDPATH to LD_LIBRARY_PATH, SHLIB_PATH or LIBPATH, see below
(the baselayout-linux.ebuild).


[baselayout-prefix-0.1.ebuild]
[baselayout-prefix-0.1_files.tar.gz]
Installs these (eprefix'ed) files:
  /etc/profile
    The entry point for this eprefix.
    Utilizes /sbin/extenv to add values the environment.
    It also sets up an alias 'eenv-clear', which sources /etc/unprofile,
    to be able to remove all the environment values for this eprefix.
  /sbin/extenv
    Interprets /etc/env.conf and generates a list of shell commands (for
    sh and csh) adding values to the environment.
  /etc/unprofile
    The exit point from this eprefix.
    Also utilizes /sbin/extenv to remove values from the environment.
    Also unaliases 'eenv-clear'.
  /etc/env.d/98secondary
    Contains values for PATH,ROOTPATH,LDPATH,... for this eprefix.
  /var/spool/emerge/doasroot
    Create it as empty file, currently not in use.
    Intention is to collect commands from enewuser/enewgroup/... when
    not run as real root (uid 0).

Additionally, two symlinks are created:
   /sbin/functions.sh -> /usr/lib/portage/bin/isolated-functions.sh
   /etc/init.d/functions.sh -> /sbin/functions.sh

I use /usr/lib/portage/bin/isolated-functions.sh because i did not know
better where to get those functions.sh from.


[baselayout-linux-0.1.ebuild]
Installs only one file:
  /etc/env.d/99system
    Only contains two lines:
      PORTAGE_ENVDUP="LDPATH"
      PORTAGE_ENVDUP_LDPATH="LD_LIBRARY_PATH"
    This configures portage (with 07-env-dup.patch) to dupe collected
    values from LDPATH into LD_LIBRARY_PATH.

Idea is to let make.profile symlink unmask different packages for hpux
and aix, to dupe LDPATH value into SHLIB_PATH and LIBPATH respectively.

Comments welcome!
