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.

One EFI + one ROOT partition is what I do on both my laptop and desktop for years, /home is a subvolume to my root partition. This setup suits my needs as I don't have to worry about how big should my root or home (gaming) partition should be.
I use Arch on my desktop and Opensuse on my laptop. They both have options to set up subvolumes from their installer, Debian does not, and I'm not sure about other distros, but you can always set that up after installation, just make your home partition the last one (after the root partition) so you can easily delete it after and grow the root partition without much blocks relocation.
I've never heard of sub volumes. What do they do for me? Why not just partition the disk or store everything on the one partition?
I like to think a subvolume is a directory on my filesystem that:
This is by no mead a definition for BTRFS subvolume, but I hope you get the idea.
