A unified kernel image (UKI) is a single executable bootable from UEFI firmware
- transfire 4y agoThis sounds awesome! So what’s the catch?
- andrewstuart 4y agoWhy would there be a catch?
- selfhoster11 4y agoThis is UEFI we’re talking about. It’s got a certain reputation.
- db48x 4y agoI see two potential snags: you can't change the kernel command line, and you cannot downgrade to a known-buggy kernel version. There is some flexibility around the kernel command line, so in practice you may still be able to use some whitelisted kernel parameters. (If your distro puts in the effort.) Lack of downgrades could be a problem. You might upgrade the kernel and find that it is broken, and that you've also lost the ability to boot your previous kernel. Both risks seem acceptable in a corporate environment, but perhaps not for the home user.
- phendrenad2 4y agoI wish BSD had this.
- stoplying1 4y agoNot a BSD guy but given what I understand this struck me as a weird comment. https://github.com/systemd/systemd/issues/18733 https://github.com/systemd/systemd/issues/18733 you sure it's not supported?
- phendrenad2 4y agoI'm pretty sure that none of the BSDs have an EFI stub option, and they need a separate EFI bootloader. I could be wrong, but I did check this about a year ago.
