I have started to develop a testing environment for unstable openwrt images.
The mission is to be able to test unstable software even on inaccessible outdoor nodes without ever loosing network access.

Idea:
- have a stable openwrt on the internal flash
- have various unstable images on partitions of the CF Card
- boot the unstable openwrt from the stable image (using kexec)
- reliable reboot automatically to the stable image if something goes wrong (using kernel+userspace watchdog)

It currently runs on the avila, mainly because my kexec port is only running on arm atm. (x86: untested, mips: not working)

The full step-by-step intro can be found on http://svn.net.t-labs.tu-berlin.de/proj … ulletProof
including links to all the required patches and packages

You say: "mips: not working".

Do you actually have kexec-tools which work on mipsel?

I tried this patch recently, but it didn't work for me - new kernel wouldn't start:

State of mips:

it seems that nobody has working kexec-tools for mips. I have browsed the web and found no positive results. I won't try to port the kexec-tools to mips on my own, but if somebody can point me to a patchset, that is claimed to actually work, then i'll happily apply it.

See here: http://lists.infradead.org/pipermail/ke … hread.html

And look for "kexec-tools: mipsel port" thread which was started today by Simon Horman.

It contains patches which should make kexec work on mipsel, hopefully.

any luck with this?
