From 2f0ef8cd0e61c34e67ad9c7508094da3c23f5fce Mon Sep 17 00:00:00 2001 From: Mikko Rapeli Date: Wed, 23 Oct 2024 15:08:33 +0300 Subject: wic bootimg-efi.py: change UKI support from wic plugin to uki.bbclass Remove custom wic plugin implementation and use systemd ukify reference implementation when generating UKI images. Fail if users still have create-unified-kernel-image in wic image config. uki.bbclass use is detected from IMAGE_CLASSES variable ("inherit uki" in image recipe) so export that to wic plugins. If UKI is used, then only generate a minimal loader config for systemd-boot which basically just sets a timeout. Also set 5 second timeout by default instead of failing if wic bootloader config is missing. Boot menu is generated at runtime based on UKI binaries found from ESP partition.
