Well Bret, assuming you have the correct UUIDs, those partitions should be
mounted in the filesystem, however, you don't mention where you expect
them to be mounted, what are you trying to achieve?

sda5 is not the /home of your filesystem, the way you have the fstab
written it is the /debian_home in your filesystem, your filesystem will
not see that as home.

sda8 is to be mounted at /data in your filesystem, nothing wrong with
that, however, remember because it's mounted in the root of your
filesystem, as a regular user, you will have limited permissions on that
folder. It's only in your home that you have permissions necessary to
write, that's part of the security model of the nix filesystem

Yes, correct. If you give the command without anything else it will output
your current mounts. I mentioned that to you previously but you may not
