Sorry to bother you again with this...
I have tried to remaster a gnap core with a alsa-utils.
'ebuild'-ing the alsa-utils:
# ebuild /usr/portage/media-sound/alsa-utils/alsa-utils-1.0.9a.ebuild
install
Making the extension:
# cd /var/tmp/portage/alsa-utils-1.0.9a/image
# tar -cjvf /usr/lib/gnap/extensions/gnapext_alsa-utils.tbz2 *
Remaster the core with the modified kernel and the alsa-util extension:
#gnap_remaster -k kernel.tar.bz2 -m modules.tar.bz2 -e alsa-utils -o
newcore.tar
Then I can create my boot image:
# gnap_overlay -g newcore.tar ....
This boots nicely and running Gentoo has all the built files from
alsa-utils. However, they won't work.
In my enthausiasm I forgot that alsa-utils is probably depending on
other packages.
And indeed:
# emerge --pretend --emptytree --tree alsa-utils
These are the packages that I would merge, in reverse order:
Calculating dependencies ...done!
[ebuild N ] media-sound/alsa-utils-1.0.9a
[ebuild N ] dev-util/dialog-1.0.20050206
[ebuild N ] sys-apps/pciutils-2.1.11-r5

[ebuild N ] sys-libs/ncurses-5.4-r6
[ebuild N ] sys-libs/gpm-1.20.1-r4
[ebuild N ] sys-devel/patch-2.5.9
I assume that some of these will probably already be available in the
original GNAP core.
But some of them I need to add.
What would be the best way to figure out which ones are already in the
original GNAP core and which ones I need to add?
Also, is there a way to 'ebuild' alsa-utils and its dependencies in one
go?
Again, thanks for the help so far..!
