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 couldn't find any documentation about this anywhere, but it seems like they do NOT work together

running Arch (btw), if that makes any difference

I don't know how to do it with systemd.automount but I've been using udisks to define defaults for mounting BTRFS: https://wiki.archlinux.org/title/Udisks#Default_mount_options

Every day we stray further from Ritchie's light.
