embedded ubuntu?

[Hervé Fache]

My experience with Crosstool, from Dan, is that most packages
cross-compile without much hassle, especially the base packages
(e2fsprogs, reiserfsprogs, modutils, this sort of stuff).

I know Dan won't push Crosstool like mad, because he's a nice chap,
but I would, because I think it's the right way to do. I don't do
cross-compilations anymore at work unfortunately, so I can't help as
much as I would love too, but if I can be of any help, or if I get a
new job that does CC, I'd be very happy to give a hand!

I used to maintain my own tools and distribution, but really, using
the existinf stuff _is_ the right way to go. Good luck guys, you rock!

Hervé.
