There was an initramfs bug recent-ish-ly, are you using a version after
http://landley.net/hg/aboriginal/rev/1366 ?

I need to provide a way to select this, do a defconfig if no  busybox
config is provided, otherwise use that.  Probably some kind of config
setting.

I'm also back to working on toybox, which means testing toybox, which
means getting toybox and busybox to install alongside each other and
gradually reduce the number of busybox commands I'm using.

I'm not inflicting toybox on aboriginal's default configuration any time
soon, but I personally need the option.

I admit the trimconfig was a bit of a hack; trying to use defconfig but
it didn't work.  And now busybox defconfig is back to not working
because the UBI stuff doesn't build on ubuntu 11.10.

I need to write my own genext2fs.  Now that I'm back working on toybox,
I may manage that eventually...

I've argued with Denys about that.  CONFIG_DESKTOP is not well defined,
there's no clear rule for what it does and doesn't do.

This config is enough to build aboriginal linux itself, with this in
hostconfig?

A) Does that include running the ./download.sh stage?

B) Have you tried lfs-bootstrap.hdc with this?
