fstab

/etc/fstab is a file that contains information about file systems.
File systems can be added by appending the file with a line in the format [device ID] [mount path] [filesystem] [mount options] [dump frequency] [filesystem checks]
- Device ID
  - Anything used to uniquely identify the drive. /dev/sdX can be used, but it's strongly recommended to use /dev/disk/by-*/[file identifier] instead, with the appropriate information filled out.
  - lsblk can be used to quickly gather the information needed
- Mount path
  - This is where the file system will be mounted; typically /mnt/folder-of-choice
    - You should create the directory first
- Filesystem
  - The format of the filesystem being mounted, e.g. ext4, ntfs, etc.
- Mount Options
  - Various options for more advanced use cases, like preventing it from being mounted with mount -a.
  - defaults will suffice for most people, and it is customary to include it in the command.
- Dump Frequency
  - Used by dump to determine which filesystems need to be dumped.
    - Defaults to 0
  - Again, highly irregular to configure; use 0 to say don't dump this file system.
- Filesystem checks
  - Used by fsck to determine the order of filechecks performed
    - 1: The root filesystem, performed first
    - 2: Any other filesystem that should be checked
    - 0: Default, no checks performed.
Example command: /dev/disk/by-uuid/123 /mnt/dir-name-of-choice ext4 defaults
- Omitting the trailing 0s because they are the defaults.
