Hi,
How is the busybox emerge work going?
I *might* be able to give a hand with the busybox emerge this week.
I have been thinking last days at least and have some thoughts.

my /usr/portage partition reports approx 200MiB (without the distfiles)

Do we really need the fetch functionality to be built in into emerge?
This is how I think and pleas correct me when/if I go wrong:
does busybox rpm support fetching?
does busybox dpkg support fetching?
would it be an idea to build a separate program/script that runs on top
of busybox emerge? Something like apt-get running on top of dpkg /rpm.
In many embedded environments will probably a fetch feature be overkill
anyway. Those who really need it could write a script like:
# the package name
PKG=$1
PKG_PATH="http://myserver/myproj/tbz2";
CACHE="/var/cache/gentoo"
# lets say Packages just contains a filelist of available packages
# in the repository
LATEST=$(wget -q -P $CACHE $PKG_PATH/Packages.gz | gunzip -c | \
grep "^$PKG-[0-9].*" )
# do error check here
wget -P $CACHE $PKG_PATH/$LATEST
emerge $CACHE/$LATEST

In any case, you could probably begin with the "install" part so it is
possible to install packages. When that is working more functionality
can be added.
Anything I could do to help?
