Embedded != Low Power

required as it is more robust for environments with moving vehicles

OK, that might be a little bit tight for a GUI based on Lenny, even with
XFCE. However, I read below that you don't need a GUI so 512Mb is plenty
of space. I'm still not sure what you want the device to do though
because amd64 is a powerful architecture and I can't imagine that you'd
get it to run without a fan or have much of a battery life if the device
is meant to be portable, which makes it hard to see the appeal of solid
Embedded != Low Power
It is true that a lot of embedded devices have limited storage,
computing power and need to be low power, but not all.
eg. Communications equipment (think managed routers/switches, vpns,
firewalls, etc) that sit in communication cabinets.
I've worked on this class of equipment and I would consider them to be
embedded products. They have mid-range embedded processors targeted for
communications (eg. PowerPC PowerQUICC) with now keyboard or video.
They generally have a serial console port and network ports for
management. This type of equipment can have 100W-500W power-supplies
with lots of fans.
I do agree that Emdebian should cater for low power, low capacity, low
speed devices, however it should also cater for higher end embedded
From memory, Emdebian Grip would be a good candidate for this, right ???
I have developed for PowerPC architecture, using Apple PowerPC PowerMacs
as the development hosts, however now that Apple have gone Intel, it
makes it harder to find powerful PowerPC platforms to build powerpc
Ideally I would prefer to use powerful commodity PCs, and cross-compile
everything I need to customize.
Ideally I could use all the pre-built powerpc debs from Lenny, and just
cross-compile new packages that I need to modify or create.
Ideally, IMHO, Emdebian should be able to totally cross-compile a
powerpc <or insert favorite arch> distribution from scratch, and produce
exactly the same outputs (.debs) as a build on the native powerpc
<insert arch> host.
Is that a goal of Debian Grip ???
