It's nice to see more people embracing the capabilities of UEFI and Linux. ZFSBootMenu has been shipping an EFI application (really, a UKI masquerading as one) for almost four years now - https://docs.zfsbootmenu.org/en/v2.3.x/ https://docs.zfsbootmenu.org/en/v2.3.x/ . The neat part is that the first stage kernel boots in roughly 1.5 to 2 seconds. It's not really appreciably slower than other boot methods while at the same time exposing a substantial amount of pre-boot functionality.

It's not really appreciably slower than other boot methods while at the same time exposing a substantial amount of pre-boot functionality. That sounds 1.5 to 2 seconds slower than just having efistub in your main kernel image, which honestly is a LOT. Of course not possible with problematic drivers like ZFS but then you don't have to use those.
- E39M5S62 2y agoYes, and then your main kernel image is no longer on ZFS and you lose the ability to reliably roll back your root dataset. Everything is a trade off. I reboot my workstation once a week for a kernel upgrade, so an extra 2 seconds of boot time isn't even a consideration.
