Below is an elaborate example of an /etc/fstab file, providing everything what is needed to properly bring up a system that is using the default partitioning scheme in combination with the default Btrfs filesystem layout:

FILE /mnt/gentoo/etc/fstabA full fstab example

/            btrfs    noatime,subvol=rootvol              0 0
   /home        btrfs    noatime,subvol=homevol              0 0
   /var/swap    btrfs    noatime,subvol=swapvol              0 0
/var/swap/swapfile                     none         swap     sw                                  0 0

To improve performance, most users would want to add the noatime mount option, which results in a faster system since access times aren't registered (those are not needed generally anyway). This is also recommended for solid state drive (SSD) users, who may also enable the discard mount option (ext4 and btrfs only for now) which makes the TRIM command work.

And this is what the /etc/fstab file would have to look like following the examples given in the instructions, if the main partition has been encrypted with LUKS:

FILE /mnt/gentoo/etc/fstabA full fstab example accounting for LUKS encryption

/dev/mapper/main_crypt                 /            btrfs    noatime,subvol=rootvol              0 0
/dev/mapper/main_crypt                 /home        btrfs    noatime,subvol=homevol              0 0
/dev/mapper/main_crypt                 /var/swap    btrfs    noatime,subvol=swapvol              0 0
/var/swap/swapfile                     none         swap     sw                                  0 0

Double-check the /mnt/gentoo/etc/fstab file, save and quit to continue.
