linux VS zen-kernel

I think that's outdated: https://github.com/torvalds/linux/commit/64bef697d33b75fc06c...

For specific cases I can find ext4 explicitly checking for RO https://github.com/torvalds/linux/blob/8c06da67d0bd3139a97f3...

FFS predates FreeBSD and is in some capacity supported by all 3 major BSDs. I'm fairly confident that Linux actually supports it through the ufs driver ( https://github.com/torvalds/linux/tree/master/fs/ufs ); whether the use of different names in different places makes it better or worse is an exercise for the reader.

These are a bit easier to see what's going on:

Unfortunately Github doesn't have a way to render symbols for whitespace, but you can tell by selecting the spaces that the previous version had leading tabs. Linus changed it so that the tokens `default` and the number e.g. `12` are also separated by a tab. This is tricky, because the token "default" is seven characters, it will always give this added tab a width of 1 char which makes it always layout the same as if it were a space no matter if you use tab widths of 1, 2, 4, or 8.

There was also a Gentoo effort to run atop FreeBSD[0]. The challenge of course is that afaik none of the BSD kernel ABIs are considered stable. The stable interface is the BSD libc. That said, with binfmt_misc, I don't see a reason you couldn't just run (at least some) FreeBSD binaries on Linux with a thin syscall translation layer (rather something like qemu-system) and then your layer hooked via binfmt_misc. I'm not aware of anyone who has done this for FreeBSD, but prior efforts existed as alternate binfmts for SysVr4/5 ELF binaries[2]. Either way would take some elbow grease, but you *might* even be able just reuse binfmt_elf and just have a new interpreter for FreeBSD elf.

Linux is configurable. If you don't want it to freeze up, configure it so it wont https://github.com/zen-kernel/zen-kernel

What do you mean fingers in the pie? And for liquorix the four people are only the ones involved in the packaging, you'll notice that they just include one huge monolithic patch here https://github.com/damentz/liquorix-package/tree/6.1/master/linux-liquorix/debian/patches/zen and to see what is inside that and whose fingers are in there you need to look into https://github.com/zen-kernel/zen-kernel and you have exactly the same situation as with xanmod with your 13k contributors.

It seems like the zen kernel "doesn't use" the same version as the upstream kernel (default). I think for now it is still on 6.0.12: https://github.com/zen-kernel/zen-kernel

Officially supported kernels Community support on forum and bug reporting is available for officially supported kernels. Stable — Vanilla Linux kernel and modules, with a few patches applied. https://www.kernel.org/ || linux Hardened — A security-focused Linux kernel applying a set of hardening patches to mitigate kernel and userspace exploits. It also enables more upstream kernel hardening features than linux. https://github.com/anthraxx/linux-hardened || linux-hardened Longterm — Long-term support (LTS) Linux kernel and modules. https://www.kernel.org/ || linux-lts Zen Kernel — Result of a collaborative effort of kernel hackers to provide the best Linux kernel possible for everyday systems. Some more details can be found on https://liquorix.net (which provides kernel binaries based on Zen for Debian). https://github.com/zen-kernel/zen-kernel || linux-zen

@OP So yeah on Linux we don't have NVE which i'm kinda glad about for various reasons. But we have gamemode (sorry for the ArchWiki entry on it) and custom kernels like Zen. If you opt to install the Zen Kernel ALWAYS keep a regular Kernel as backup, just in case.

I was afraid that disabling dm-crypt workqueues caused it: https://github.com/zen-kernel/zen-kernel/issues/282
