Re: [PATCH 3/4] Add support for building for other architectures
Hey,
Hmm, this didn't actually work, as it turns out. I'd only ever used
this method for building i386 on amd64, which does work. Trying to use
it for other architectures blew up.
I am working on a better approach using the second-stage mode in
debootstrap and qemu, but it's after 00:30 my time, so I'll continue
work on this tomorrow.
The main reason I'm adding this feature is I was talking to friend at
the OpenStack Summit a few days ago who complained that people don't
tend to support architectures which aren't amd64. The context was
Docker, but I think extending that to cloud images is fair.
Cheers,
Andrew
