Hey Ludo,

Yes my point is that building three specifications on three
architectures, including an emulated one, is already hard for the build
farm, so adding more specifications/architectures seems complex.

Even if we fix the problem raised by Danny, enabling again ARMv7
transparent emulation, without any additional hardware wouldn't fit.

Yes, that's solved by the remote building feature. The workers are
declaring the architectures they support. When they request work, the
remote server picks randomly an architecture and select the most
priority build available. This way the queuing happens at the database
level and not in the guix-daemon itself.

Thanks,

Mathieu
