Hello, I saw that we can get ramdisk image from tarballs.openstack.org[1] in ironic doc[2]. I would like to ask whether all the above are of amd64 architecture. Where can I download the ramdisk image of aarch64 architecture？ When I built aarch64 image locally, It's always failed. ```shell # export ARCH=aarch64 # ironic-python-agent-builder fedora ... mount: /tmp/tmp.1yEQhatS1X/mnt: wrong fs type, bad option, bad superblock on /dev/mapper/loop0p5, missing codepage or helper program, or other error. # ironic-python-agent-builder centos ... 2023-02-12 14:15:02.361 | dib-run-parts Running /tmp/in_target.d/pre-install.d/01-00-centos-python3 2023-02-12 14:15:05.204 | CentOS Linux 8 - AppStream 17 B/s | 38 B 00:02 2023-02-12 14:15:05.209 | Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist # ironic-python-agent-builder ubuntu ... 2023-02-12 14:15:31.623 | Fetching Base Image 2023-02-12 14:15:31.657 | % Total % Received % Xferd Average Speed Time Time Time Current 2023-02-12 14:15:31.657 | Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 2023-02-12 14:15:32.388 | Server copy has not changed.
