I’m just finished with adding Travis CI to the VDR4Arch project to make Travis CI build our Arch Linux packages: https://github.com/VDR4Arch/vdr4arch
As a next step it may really be interesting to also build for ARM 32 (I hope a 32 bit chroot will work on your ARM64 setups).
Could this actually work? How well does building for ARM64 work?
And if I try this: How would I deploy my packages? Can I disable parallel building so the two machines don’t delete each others packages? Or would I have to make each instance deploy to their own GIT repo?
