mntsubvolNAME

mntsubvolNAME is a placeholder used in Linux documentation and scripts to denote the mount point for a btrfs subvolume named NAME. It is not a real command or feature; it simply represents the convention of mounting a specific subvolume to a designated directory.

In practice, a subvolume under a btrfs filesystem is mounted by specifying the subvolume name in the mount options. A typical workflow is:

- Create a mount point, for example: mkdir -p /mnt/mntsubvolNAME

- Mount the subvolume: mount -t btrfs -o subvol=NAME /dev/sdXN /mnt/mntsubvolNAME

Here, /dev/sdXN is the underlying btrfs filesystem device, NAME is the subvolume’s name, and /mnt/mntsubvolNAME is the chosen mount point. The exact paths will depend on your system configuration.

To make the mount persistent across reboots, add an fstab entry such as:

/dev/sdXN /mnt/mntsubvolNAME btrfs rw,subvol=NAME 0 0

Notes:

- If you want to mount the root subvolume (the default subvolume within the filesystem), you would typically omit the subvol option or use subvol=/.

- The concept of mntsubvolNAME is widely used in examples but may vary in actual implementations; replace NAME and paths with values appropriate for your setup.
