Re: [gentoo-embedded] PPC embedded base package

Hi,

Thanks for the reply, I'm sorry it took so long to get back to you, but
I never received an email to me until the digest caught up.

We're working on a small NAS-like device.  Very light weight, and
targetting to consumers rather than businesses, so everything will be
pretty simple.

I'm currently working on getting a 2.6.x kernel up on the early boards.
Once that's up and running, I'll be working on the rootfs.  I've been
doing a lot of checking as far as dependencies go, and I've got the
libraries narrowed down substantially.  We're also using the 2.2.x samba
branch, since the 3.x branch requires a large number of libraries that
we don't want to include.

I've been ensuring that every binary going into the image is stripped so
far as well.

I guess I was kind of hoping that the gentoo embedded group was working
with small root filesystem sizes, and whether or not there was a base
layout package that would simply contain things like pre-populated /dev,
and other absolutely essential sources like that.

Are there any plans for such a package?  Perhaps with makefiles that
would leverage cross compilers to create a base system for target X on
host Y?

It would make embedded development incredibly easy with cross compilers
and base layout packages of that sort ready to be emerged into /opt or
something like that.

Thanks,
Anthony
