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.

Bcachefs has filesystem encryption without LUKS? Did this have an audit? I use BTRFS and it is fine, but boot is unencrypted (using TPM would be cool)
https://en.wikipedia.org/wiki/Bcachefs
I see it has an audit back in 2017, but I've yet to find anything newer. The finding was good, but suggested further audit be done.
I dont see the difference to BTRFS apart from encryption and maybe caching? I was always confused why people hype it so much.
Interesting, yes I wouldnt not use LUKS if the alternative is less known, not used by enterprise distros
The tiered storage stuff is pretty cool. You can say "I want this data on this disk, so if I get a cache miss from a faster disk/RAM it'll come from this other disk first."
I believe it also has some interesting ways of handling redundancy like erasure coding, and I thiiiink it does some kind of byte-level deduplication? I don't know if that's implemented or is even still planned, but I remember being quite excited for it. It was supposed to be dedupe without all of the hideous drawbacks that things like ZFS dedupe have.
EDIT: deduplication is absolutely not a thing yet. I don't know if it's still on the roadmap.
EDIT: Erasure coding is deffo implemented, however.
