Suggestion: Validate fstab step

In the section about editing /etc/fstab, it would be nice to direct users to run something like `findmnt --verbose --verify` in order to validate the correctness of their fstab entries, saving some pain later.

Doing a fresh install from the gentoo live CD, here's some output of a mistake it caught in my fstab:

chroot ~ $ findmnt --verbose --verify
/boot
   [ ] target exists
   [ ] VFS options: noatime
   [ ] userspace options: noauto
   [ ] UUID=ADCD-9B0E translated to /dev/nvme0n1p1
   [ ] source /dev/nvme0n1p1 exists
   [W] fat seems unsupported by the current kernel
   [E] fat does not match with on-disk vfat
none
   [ ] UUID=45970879-625b-4638-bae6-82515ebc4687 translated to /dev/nvme0n1p2
   [ ] source /dev/nvme0n1p2 exists
   [ ] FS type is swap
/
   [ ] target exists
   [ ] VFS options: rw,noatime
   [ ] FS options: commit=90
   [ ] UUID=78cad2f9-f305-4b68-b090-edf5511078d0 translated to /dev/nvme0n1p3
   [ ] source /dev/nvme0n1p3 exists
   [ ] FS type is ext4

0 parse errors, 1 error, 1 warning

Which alerted me to fix the FS type on the boot line. Rerunning, here's what stdout looked like with the valid fstab:

chroot ~ $ findmnt --verbose --verify
/boot
   [ ] target exists
   [ ] VFS options: noatime
   [ ] userspace options: noauto
   [ ] UUID=ADCD-9B0E translated to /dev/nvme0n1p1
   [ ] source /dev/nvme0n1p1 exists
   [ ] FS type is vfat
none
   [ ] UUID=45970879-625b-4638-bae6-82515ebc4687 translated to /dev/nvme0n1p2
   [ ] source /dev/nvme0n1p2 exists
   [ ] FS type is swap
/
   [ ] target exists
   [ ] VFS options: rw,noatime
   [ ] FS options: commit=90
   [ ] UUID=78cad2f9-f305-4b68-b090-edf5511078d0 translated to /dev/nvme0n1p3
   [ ] source /dev/nvme0n1p3 exists
   [ ] FS type is ext4

Success, no errors or warnings detected
