No, the current Samba top-level build doesn't even work on 128 MB of RAM
without using swap. It actually might be nice to fix that at some point

As Chris indicated, targeting 32bit might be worthwhile, current ARM
platforms are 32bit. I think the focus on ArchLinux in the discussion is
unfortunate, there's a lot of distros that are less braindead in their
approach towards packaging python that also work on ARMv5.
ArchLinux shipping with a broken python default setting is an orthogonal
problem, in my opinion.

I've got a dual-core 1 GHz A9-Cortex box with 1 GB of RAM and an SSD
drive. If that's not fast enough for the build farm, we can simply give
up testing for embedded devices and tell people we don't support low-end

Is this documented somewhere? Getting hold of a new system for the build
farm just to get shot down a couple of days later seems like an
inefficient approach to getting a box in.
If the build farm is not the place to make sure we support embedded
devices, what _is_ the proposed method? Do I just run a cron-job based
build on one of my systems that checks if make test worked and then
emails all authors of the git commits between the last build that worked
and the current one that failed?
