Would be interesting to have a proof of concept, e.g. a server VM image. However, when I look at the ARM SBC UEFI, some improvement would be desirable. At the moment, there is only a crumpled UEFI image flying across the screen, without any intervention option (which is OK for SBC, but probably not for a „real“ server). -- Peter Boy https://fedoraproject.org/wiki/User:Pboy p...@fedoraproject.org <mailto:p...@fedoraproject.org> Timezone: CET (UTC+1) / CEST /UTC+2) Fedora Server Edition Working Group member Fedora Docs team contributor and board member Java developer and enthusiast
