On `bootctl install`, two EFI boot entries are registered: one for the primary sd-boot binary and one for a fallback. On `bootctl update`, the existing primary binary is rotated to the fallback path before the new version is installed, so the fallback entry always points to the previous known-good binary. ``` $ sudo bootctl install ... Created EFI boot entry "Linux Boot Manager". Created EFI boot entry "Fallback Linux Boot Manager". $ sudo bootctl update Copied "/boot/EFI/systemd/systemd-bootaa64.efi" to "/boot/EFI/systemd/systemd-boot-fallbackaa64.efi". Copied "/usr/lib/systemd/boot/efi/systemd-bootaa64.efi" to "/boot/EFI/systemd/systemd-bootaa64.efi". $ efibootmgr ... Boot0004* Linux Boot Manager HD(...)/\EFI\systemd\systemd-bootaa64.efi Boot0005* Fallback Linux Boot Manager HD(...)/\EFI\systemd\systemd-boot-fallbackaa64.efi ``` Fixes: #23805
