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.

Seriously?
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.
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.
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.
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-tools
due 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.
This is a bot lollllll
Not all of us know what this is. Can you expand on your thoughts?
Agreed!
I don’t know what this is but it is a topic I am somewhat familiar with and it is somehow significant enough to be a headline.
Curious minds would like to know more.

Thanks!
Yes I'm asking for the reason why you think this development is good. It seemed to me like it could have worked out if they talked it out and could have added something of value to the OS
Very easy to search, but you're lazy so:https://hackaday.com/2025/06/10/the-ongoing-bcachefs-filesystem-stability-controversy/
It’s not lazy to ask someone who seems to know something about the topic within a discussion thread about said topic. You know more than I do on this.
I understand how you may not want to take the time to answer someone’s question but also you could have replied with the link you eventually did instead of saying “Seriously?” Within the context of calling others lazy you could also qualify under the same term since you took the time to respond but not with the answer.
With search being what it is nowadays I wouldn’t know if I am getting a good result to find out the answer since it is of a technical and specific nature I may or may not even know if I am familiar with to begin with. It could take me much longer to figure it out, or I will give up and not be interested in finding out more about a field you seem to have an interest and knowledge about and I am demonstrating I want to know more about.
I think it is fair to ask for more information from someone who shows more expertise in the topic before searching.
It is
no u
I've heard about this and wanted to hear your opinion on it because you seemed to have gotten to another conclusion than I have. But it seems that you're not interested in discussing so I'm no longer interested
There's no reason to be rude and insulting. It doesn't make the other person look lazy; it just makes you look bad, especially when you end up being wrong because you didn't do any research either. The article is garbage. It's obviously written by someone who wants to talk about why they don't like bcachefs, which would be fine, but they make it look like that's why Linus wanted to remove bcachefs, which is a blatant lie.
But if we click on the article's own source in the quote we see the message (emphasis mine):
Stability has absolutely nothing to do with it. On the contrary, bcachefs is explicitly expected to be unstable. The entire thing is about the developer, Kent Overstreet, refusing to follow the linux development schedule and pushing features during a period where strictly bug fixes are allowed. This point is reiterated in the rest of the thread if anyone is having doubts about whether it is stated clearly enough in the above message alone.
Ohhhh nooooo 🙀
