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.

Wait til your table with all the checksums gets messed up on an “older” btrfs install. Happened to me on a VM because I didn’t know copy-on-write should be disabled for large frequently partially updated files. It also slowed that VMs IO down a lot.
Like most file systems, BTRFS is great if you know the edge cases. I recently moved to ZFS on my new work system, which has been a great change in terms of in-line snapshots and the like.
If EXT4 meets your needs, that’s awesome. If you understand how to use a different FS well or are willing to learn (and risk), I would also encourage other options as well.
