💾 Mount Visual Editor (fstab)

About the fstab Visual Editor

/etc/fstab (the filesystem table) is a configuration file on Linux and Unix-like systems that defines how disk partitions, network shares, and virtual filesystems are mounted automatically at boot time. Each line describes one filesystem and the parameters to use when mounting it.

The six fstab fields

• Device — identifies the filesystem: a block device path (/dev/sda1), a UUID (UUID=abc123), a LABEL, or a network path such as //server/share for CIFS or 192.168.1.1:/share for NFS.
• Mountpoint — the directory where the filesystem will be attached, e.g., /, /home, /mnt/data. Use none for swap.
• Type — the filesystem type: ext4, xfs, btrfs, ntfs, vfat, tmpfs, nfs, cifs, swap, and others.
• Options — comma-separated mount options such as defaults, noatime, ro (read-only), nofail (do not abort boot if mount fails), and _netdev (wait for network).
• Dump — 0 to skip, 1 to include in backups made by the dump utility. Almost always 0 on modern systems.
• Pass — fsck check order at boot: 0 = skip, 1 = check first (root filesystem only), 2 = check after root.

Why use UUIDs instead of device paths

Device names such as /dev/sda1 can change between reboots if disk enumeration order changes (for example when adding or removing a drive). Using UUID=... — obtained with the blkid command — uniquely identifies a partition regardless of its device name, making mounts stable and predictable.

How to use this tool

• Import an existing /etc/fstab by pasting its contents — the tool parses each line into the visual table, preserving comments and disabled entries.
• Build Entry to configure a new mount with guided inputs, option chips, and common presets for root, home, EFI, swap, NFS, CIFS, and tmpfs.
• Toggle the checkbox on any row to comment it out (disable) without deleting it.
• Download exports a ready-to-copy /etc/fstab file. Document exports a Markdown or Excel reference of your full mount configuration.
