# A bunch of predefined filesystem configurations for several devices. This is

|
|
# conflicting settings all throughout the configuration.
|

# Much of the filesystem setups are taking advantage of systemd's fstab
|
|
# extended options which you can refer to at systemd.mount(5), mount(5), and

# the filesystems' respective manual pages.
