I’ve removed Arch Linux from the automated tests due to complications within Terraform. These issues were sort of the final straw in my Arch testing efforts.
The Arch community doesn’t supply an official AWS AMI. I had been relying on a privately built AMI that isn’t 1:1 with a manual Arch installation. For perhaps the last half year, my Arch tests were failing but the installer worked if you tested it against a manually setup Arch installation. This can only be due to differences between the AMI I was using and a manual installation.
The Arch community is vehement about only providing help if you follow their installation instructions on their wiki exactly. Because of this, when I asked for some help sorting out the issues, they were not willing to help.
Until someone with some Arch prowess can put some time into helping with this, Arch Linux will not be included in the automated tests.
