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.

No, comment is not true. You can use ZFS or BTFS, both of which are open source. ZFS just happens to be historically funded by Oracle, which is a good thing.
The reason is bcachefs has ~~major~~ stability problems (that don't allow it to meet kernel release schedules). https://hackaday.com/2025/06/10/the-ongoing-bcachefs-filesystem-stability-controversy/

Oracle funding doesn't sound like a good thing at all since they're basically CIA cloud ran by one of the most influential Zionists. But an unstable filesystem sounds even worse.
Everyone always says "Companies should fund FOSS instead of spending money on big corpos!", yet then this.
It's FOSS. It's auditable. Funding is a good thing.
That's true, but we also know that funding can come with stipulations. Oracle is an especially sketchy company.
But that counts for all big tech I guess.
In this situation it works well, IMO. For some more context, ZFS was created by Sun (FOSS). Oacle bought them and built Oracle ZFS out of it. OpenZFS forked at that point from Sun code, and that's what we use in Linux/etc. The Oracle variant supplies support to the FOSS variant. So Oracle has no control over OpenZFS.
So not using Linux at all then? Most of the development is paid for by big tech.
My comment moreso pertains to the "which is a good thing" part of the previous one.
Google managed to backdoor Linux and Firefox with their "FOSS" libWebp. Took literally years until some security researcher not affiliated with any of them found the bug by chance and made a public report, and by then it had already been explited by NSO for ages. If they had worked for Google (or Apple/Microsoft/Amazon/any of the other corporations that just imported Google's libWebp code without looking at it) they would have gotten silenced and the exploit would still be there as a gift to Israel. Turns out just because it's auditable doesn't mean it gets audited before it's too late.
And so have countless closed-source developers/companies/applications. A vulnerability existing does not change the fact that FOSS projects should be funded more.
Open ZFS is now the main branch as far as I remember.
Thank You!!
“Major stability problems”. Hilarious. Get one person that actually uses bcachefs to confirm that. Good luck.
Kent has stability problems and drives me crazy but that is a baseless hit piece. Bcachefs is a solid fs.
Linus has not pushed back on the quality of bcachefs other than to say it is too unproven to rely on (too new). What Linus objected to was the process violations and the attitude of the lead developer.
Given how much Linus and the other LKML devs wanted to get rid of Kent, the fact that it took so long to dump him tells us that they really wanted to keep bcachefs (the technology).
There may have been more data loss bugs in btrfs and even OpenZFS than bcachefs since it was added to the kernel. I have many bcachefs systems. I have one btrfs system. Guess which one has caused me problems.
Fair enough on "major". Edited that. But it has stability issues that aren't handled well enough for RCs, so it's not a hit piece to state that fact. Those stability issues may come from it being new, but it's still an issue. Saying it's because they want to "get rid of Kent" is just as much of a hit piece, too.
The dev is unstable. And he made the kernel process chaotic. But the filesystem itself is pretty solid. Do you have a link to stability issues?
My understanding is the stability risks come from active development additions vs "fixes" during that stage of the development cycle.

YMMV, but my production systems will stick with ZFS since it's kernel release updates are clear when there are "upgrades" vs "updates", as you do those manually when it alerts you.
"Stable" in this context doesnt mean "your PC will definately crash and you will lose data!", bcachefs is well past that. It means that the development is too active to be considered production ready since the code changes are too large to confirm the scary bit won't happen (as much as can be).
Even JC threw in the towel on
bcachefs-toolsdue to this: https://www.phoronix.com/news/Debian-Orphans-Bcachefs-ToolsYou certainly don’t have to use bcachefs. I love it but several of my systems will come off it Joe that it is out of the kernel. But not for technical reasons.
It is not that he changes were scary. Nobody had a problem with the changes. It was entirely process. It was “when” the changes were being submitted.
Kent always sent stuff in after the merge window. And when Linus rejected them, due to timing, Jent would throw a massive fit and start insulting everybody. Ironically he would complain about having to put up with “drama” from Linus.
So, Linus kicked him out.
Nothing to do with the code.
