I would be happy to work with you on this - however, I also saw on
Planet Gentoo something about a gentoaster project - possibly related?
What I have is a very simple portage-a-like to support the case that I
have several stages to my script.
- Mounting all necessary sources
- Building a base system
- Copying base to target ready to be imaged
Additionally I am trying a packaging system using aufs + squashfs, so I
am building more than one target image and the whole gets stacked
together at the end
The scripting is fairly simple, but I guess this could develop into some
Arguably this is re-inventing catalyst, but speaking from inexperience,
catalyst appears to work best when the ebuilds are perfect and need to
micro patching - for embedded builds some flexibility is very helpful.
Patching ebuilds in mind: I have been experimenting with
/etc/portage/patches and also the bashrc for broad patching, eg where
some long standing patch or config customisation is necessary (eg delete
some openrc file which makes no sense, or customise some udev config, etc)
I guess if we could get this well written up then it would encourage
others to look at gentoo for embedded development? At the moment it's
very powerful, but I sense there is a steep learning curve while you
develop your own build environment?
How do you think we should proceed?
