[ubuntu] Change mount /media/username to /home using fstab didn't work

Hi, I forgot to set my home partition to /home mount point during a clean reinstall so it automatically was mounted at /media/username.

Instead of starting over the reinstall, I defined the UUID in fstab, mounted, then changed /media/username to /home in fstab and mounted again. At first all the files disappeared from all the directories involved. After reboot, I have the default empty directories in /home and nothing under /media. Even the partial backup I made in a new folder (/media/home) disappeared.

I'd really appreciate an explanation of what might have happened. Please let me know any additional information I can post.

Thanks and be safe, everyone.
