+1; actively working towards that. Unfortunately the list of dependencies for that is getting quite long (need to upgrade minimum supported toolchains, need to upgrade buildbots). Right now, I'm focused on cross compiling such that I have only 1 buildbot I need to sysadmin/devops for.  That should let me spin down all of our other build bots, such that upgrading dependencies for CI only needs to be done in one place.  In particular, our RISCV64 buildbot seems to be running a fork of debian that hasn't been updated (because there is no updated image or any updated packages) since the initial system image was created...
