# After editing this file, run 'systemctl daemon-reload' to update systemd # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info. # Accessible filesystems, by reference, are maintained under '/dev/disk/'. # Created by anaconda on Fri Mar 12 12:26:55 2021 Here's an example of an /etc/fstab file on a Fedora system: $ cat /etc/fstab

While this file has played an important role over the years, its format has changed with the introduction of UUIDs and, on some systems, a more reliable file-system type. It contains information that allows the system to connect to disk partitions and determine where they should be mounted in the file system. The /etc/fstab file is a very important file on Linux systems.
