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.

UEFI forum made it a requirement for motherboard constructors (hp, dell, msi...) to make their UEFI implementation to be able to at least read fat(12/16/32) filesystems. That is why you need a fat(12/16/32) partition flagged ESP (efi system partition) for holding your boot files.

So, I dont think you can do that unless you fall back to the old outdated BIOS or you have some *nix filesystem in your uefi implementation which I dont trust.

You're only partially correct. /boot doesn't have to also be your EFI partition. In fact, most distros by default will separate the two, with the EFI partition mounted at /boot/efi and /boot being a separate ext4 based partition. My suggestion is that, if you're running BTRFS, you should merge /boot and / as one partition. You're still free to have a FAT32-based EFI mounted at /boot/efi or better yet /efi.

I use systemd-boot and my mount point is /efi. /efi/EFI/ is where my bootloaders live.

If I rollback to an old enough snapshot, I have to reinstall my kernels from a chroot. It'd be cool if I could get around that.

Where's your /boot?

[–] yum13241@lemm.ee 1 points 1 year ago

Separate FAT32 part.
