Last time I enabled secure boot it was with a unified kernel image, there was nothing on the EFI partition that was unsigned.

Idk about the default shim setup but using dracut with uki, rolled keys and luks it'd be secure.

After this you're protected from offline attacks only though, unless you sign the UKI on a different device any program with root could still sign the modified images itself but no one could do an Evil Maid Attack or similar.

The point with m$ keys was that you should delete them as they're used to sign stuff that loads literally anything given your maid is insistent enough.

[note: it was mentioned in the arch wiki that sometimes removing m$ keys bricks some (which exactly wasn't mentioned) devices]

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
