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.

You can use btrfs with any distro. It's just easier to install on some than others. Ubuntu and Mint will automatically create subvolumes for root and home if you install on a btrfs partition. With Debian, you have to manually create and mount all of the subvolumes before starting the installation.
Except CentOS/RHEL. RH doesn’t build the kernels with btrfs support.
It was available as a technology preview in RHEL 6 and 7, but dropped in 8. There apparently wasn’t much demand for it, and the reputation of BTRFS isn’t exactly synonymous with the image of reliability Red Hat strives for. There’s also the idea of maintenance and support burdens, and Red Hat themselves have launched their own stab at a fs with an integrated volume manager called Stratisd, though IBM supposedly absorbed the team that was working on it for their own products.
Just in time for Fedora to use it by default and create some interest. I get the maintenance burden though, RHEL patches their kernel like crazy. They still use XFS as default which I think is pretty unique at this point.
They don’t have any devs to support it. The one dev who an idea about btrfs left for Oracle, from what I’ve read.
Btrfs is rather nice in the correct scenarios, and lack of btrfs is one reason I’m moving away from CentOS servers.
You can't really use it with redhat. You can swap the kernel and install the user space tools, but then you won't get support from redhat.
Is anyone here using RHEL support, and is also able to mess around with their partitions?
The free licences are unsupported, and I doubt people are dropping $300+ for RHEL every few for their personal desktop.
