# Basics
The ordering of `/etc/fstab` is
1. disk
2. mount point
3. filesystem type
4. options
5. dump
6. pass
E.g.:
```
UUID=877f14e8-4738-46b0-884f-ba330dad1a7d /mnt/biggie ext4 nofail,rw,relatime 0 2
UUID=B21648C416488AF5 /mnt/share ntfs nofail,rw,nosuid,nodev,user_id=0,group_id=0,allow_other,blksize=4096 0 0
```
## 5: Dump
Ignore this obsolete option.
## 6: Pass
| Number | Meaning |
| | |
| 0 | Swap (or not mounted) |
| 1 | Mount at / |
| 2 | Mount somewhere else |
## Options
- `nofail` means the computer will not fail to boot, even if the drive fails, or is unplugged. It's a good option for everything except `/`.
- noauto means 'don't mount on boot' (but you can still mount with `mount -a`).
