I have lately been working on a better Linux kernel support for it, and things are now getting in pretty good shape. I now would like to spend some time on tuning our distribution for our robots based on OE and Angstrom and I have a few questions about them. Maybe most of them have been answered in the list already, but I have had some issues following the list lately (mostly due to my military last 5 weeks). - I had filled up bugs on the bugzilla for new features (http://bugs.openembedded.net/show_bug.cgi?id=4960, http://bugs.openembedded.net/show_bug.cgi?id=4961, http://bugs.openembedded.net/show_bug.cgi?id=4971, http://bugs.openembedded.net/show_bug.cgi?id=4972). I have read that the preferred way to submit patches is the mailing-list. Should I repost the (maybe updated) recipes to the mailing-list and close the corresponding bugs ? I think that the answers to the questions below may trigger new discussions so I will repost the updated recipes for further discussions later. - Rootfs location: We have a pretty small flash on our system (32 MB). But whe have and SD card reader. I would have these two possibilities: 1) Have a minimal image that fits in the flash with the kernel, but the rest would go to the SD card (and all packages installed afterwards too). This would allow the system to boot without a SD card. 2) Have the whole filesystem on a SD card (then, an SD card would be needed for the system to boot). Is it possible to have two different image types that would allow me to build systems for these two possibilities. - Package installation location: As stated above, since we have a small flash filesystem, I would like all the additional packages that would be installed get installed to a location that physically correspond to a SD card. How can we configure opkg so that the packages are installed into a certain location ? - Add additional feeds location: By default, with angstrom, the feed source on the angstrom-distribution.org web server in configured. Most of our robots wont have internet access, they will however have access to a server where all the packages are going to be built and I would like to add this server as the main repository. How can the system configured in that way ? - Best way to build and distribute SDK: I had proposed in the above patches recipes to build an approrpiate SDK for our system. I would like to distribute this SDK to all the people who are going to develop on our robots. I would like to keep it as simple as possible for them, so if they don't have to use OE themselves is much better. I have seen that things have been changing a bit lately about the SDK (canadian SDK, what is it exactly ?). What is the best way (best current example) so that I can build an easily distributable sdk ? Is it possible that we produce .deb files ?
