That sounds pretty good to me too. I'd be happy to implement whatever
the general consensus is :)

OK, understood.

If the defconfig isn't upstream, I'd need to provide both a config and a
postinst script, and whoever is replicating the build needs to point the
config to the postinst script correctly. Having the dropbear server
available as a simple config option allows me to either use a defconfig,
or provide a single defconfig file, to allow others to build a
petitboot-compatible builtroot image, without having to mess around too
much.

Cheers,


Jeremy
