Using the 18.04.1 server-live installer with manual partition, the system ends up with an fstab like this:
UUID=d94e7ea3-9785-11e8-b625-080027681a6b / ext4 defaults 0 0 UUID=d94e7ea2-9785-11e8-b625-080027681a6b /boot ext4 defaults 0 0 /swap.img none swap sw 0 0
fs_passno is is 0 for all file systems. fstab(5), however, states:
The sixth field (fs_passno). ... The root filesystem should be specified with a fs_passno of 1. Other filesystems should have a fs_passno of 2.
