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.

I'm going to switch from BTRFS at some point, but at this point that's going to be a few years down the line.
Btrfs never really worked out for me (I think default COW doesn't play nice with VM images) and ext4 works great.
You can disable COW for specific files btw
gods, imagine saying this to a normal user
"what the fuck is a file?"
Normal users don't have VM images...
Gnome boxes and libvirt do it automatically for their VM directories… it works and a normal user doesn’t have to know a bunch.
that's really good to know! thanks
Ext4 is faster, but I love BTRFS not just because of CoW, but subvolumes as well. You could probably get something similar going with LVFS, but I prefer that to be baked in, hence why I'm waiting for bcachefs, because it'll up the ante with tighter integration, so that might translate to better performance.
Notice my use of the word might. BTRFS performance is not so great.
Ext4 on personal computer and ZFS on my server
