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.

What about bcachefs excites you? Like, what does it offer that ext4, Btrfs and zfs don't?
Initial benchmarks show better performance than btrfs (at least for some workloads), but more importanty, I like that it offers tiered/cache storage - so you can use a fast and small drive (NVMe) to speed up a slow and bigger drive (HDD). You can do that with ZFS as well of course, but it doesn't have the massive RAM requirements. Also it's much more easier to set up and configure in comparison.
It's like btrfs, but faster, and less prone to data loss.
Btrfs is data loss prone? OpenSUSE Tumbleweed uses it as default, I assumed it was good enough.
BTRFS is honestly really great and has been for the last few years. Dont take the word of random people on the interwebs, check out some modern sources of info on the subject. Some people love to complain about RAID5/6 but if you use BTRFS the BTRFS way then it is solid.
With that said, if you dont need snapshots, drive mirroring, sub volumes, bit rot protection etc then EXT4 is hard to beat for reliability.
Snapshots changed my life. And I don't exactly demand ultra reliability for my home PC. Thanks for the feedback!
Thats why I'm still on trusty old ext4. Dunno if this is true but I dont want to risk data loss.
Ext4 just went through a data loss fix in the kernel, too.
Its got a closer feature set to ZFS (tiered storage is going to be huge for me personally), but a much friendlier license. ZFS's licensing drama solidly convinced me not to touch it with a ten meter pole. BTRFS isn't bad as well, I currently use it, but tiered storage is excellent. Was the only reason I used to consider ZFS, but becachefs is getting to have my cake and eat it too.
