Ok, I’ve made significant updates to the packaging and they are ready for more widespread testing.
Please look at this PR: https://github.com/snapcore/snapd/pull/3649
You can build snapd from this branch by going to the packaging/arch directory and running makepkg -sir. Note that this does not use your local tree but instead clones the master from github. This is not yet ready for integration with spread and local built package testing but this is a first step. My goal was to make it easy to update the Arch package in the community repository.
I’m also considering adding a snapd-git AUR package that would always track master. This could give us some more hands-on beta testing.
