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 file systems are you using on your devices and why? (en.wikipedia.org)

I want to learn more about file systems from the practical point of view so I know what to expect, how to approach them and what experience positive or negative you had / have.

I found this wikipedia's comparison but I want your hands-on views.

For now my mental list is

NTFS - for some reason TVs on USB love these and also Windows + Linux can read and write this
Ext4 - solid fs with journaling but Linux specific
Btrfs - some modern fs with snapshot capability, Linux specific
xfs - servers really like these as they are performant, Linux specific
FAT32 - limited but recognizable everywhere
exFAT - like FAT32 but less recognizable and less limited

I am now all-in on bcachefs. I don't like btrfs, cause you still sometimes read about people loosing their data. I know that might happen with bcachefs too since it's early days still but fuck it. I like the risk.

Filesystem level compression and encryption are so nice to have.

That was only on RAID setups. So if you have only a singular disk, as opposed to an array, you're fine. And that issue has been fixed for a while now anyways.

I've been running btrfs on my laptop's root partition for well over a year now and it's fine.

True true, I'm planning to go balls deep too since it have good raid capability

I get the feeling I’ll become a bcachefs fan for those reasons in the future (I tested it on a spare laptop as soon as 6.7 got into Debian Testing), but for now, I use a mix of ext4 and btrfs, as bcachefs-tools isn’t in Testing. It is trivial to apt-pin, but I try not to make FrankenDebian a regular thing. I have a feeling that they’ll iron it out and Bcachefs will be an option in Trixie by the tome it hits stable, if still with a /boot partition considering the slow state of Grub support.

I think Linux users must have some touch of masochism. Also this might interest you: https://www.phoronix.com/review/linux-611-filesystems But me too, I've just installed Cosmic DE PopOS 24.04 for my main laptop.
