tinkering with

/etc/fstab

can be dangerous.

Last time i did something wrong the system would not reboot properly and send me to the

Control+D

rescue screen where i luckily simply could type:

vim /etc/fstab

to correct the problem.

you can try your fstab settings WITHOUT (!) a reboot by terminaling:

sudo mount -a

There is no need to reboot – unless you have an encrypted file system.
