I accidentally skipped the step "Preparing fstab for the switch" and moved on to the next step of "Moving /home into /old_home" under the documentation for setting up a separate home partition here: https://help.ubuntu.com/community/Partitioning/Home/Moving
Is it okay to just do the step "Preparing fstab for the switch" from here or do I have to undo "Moving /home into /old_home"? Is so, how may I do that?
Will editing the fstab file after cd / && sudo mv /home /old_home && cd / && sudo mkdir -p /home
harm my computer?
