Maybe we may want to put these variables into terraform*.conf and remove the case sentence here

I understand your suggestion; however, MIRROR_URL currently varies across etc/terraform*.conf files (official or Azure source), while these MIRROR_BINARY_URL and MIRROR_BINARY_SECURITY_URL should use the official source and remain consistent. Moving them into etc/terraform*.conf files would introduce duplication, conflicting with the single source of truth principle.

I don't think we release stable arm64 images soon because it needs testing, could you rename this file to etc/terraform-daily-8.0-arm64.conf?

Also you should update the comment i386, amd64 or all in terraform*.conf.

I believe etc/terraform-arm64.conf (similar to etc/terraform.conf) is intended for local builds and testing. Perhaps I should add a etc/terraform-daily-8.0-arm64.conf to align with etc/terraform-daily-8.0-azure.conf?

I'm a bit confused about the configuration here. I noticed that daily builds are set with HWE_KERNEL="no", while stable builds use HWE_KERNEL="yes". Could you clarify the reasoning behind this?
For ARM64 specifically, since mainline kernel support for most hardware is still a work in progress, the HWE kernel may perform better.
I think this is because the installer is only built for amd64 at the moment, maybe because we only provide arm64 image for Raspberry Pi and PineBook Pro, which users write images to SD cards directly and don't use the installer. The above file you mentioned is generated from this and it's simply ignored if there is no such package in the each architectures. |

I just copied latest distinst to the patches PPA which should also have support for arm64 |
This PR introduces native ARM64 build support. Related to #682.
Thanks to @t3rminus for the initial attempt.
Current limitations:
live-buildis required.io.elementary.installerpackage is currently not included in metapackages/live-arm64, preventing installation to disk.Tested using UTM on Apple Silicon Mac.
