Well spent the morning banging my head against the wall. I can add to fstab, I can get it to show up on the login screen but I am stopped by the "Startup Config Doesn't Exist" error. Tried reinstalling and I get the same error. The error the first time didn't occur before I added the partition the first time. Didn't test after the second install. Googel did'nt really have anything.
Precisely what you've done is still a bit unclear. But:
If you mount a new partition at
/home it will replace (cover) everything that used to be in the
/home directory.
To log in with the new
/home partition it must have a subdirectory
/home/<user> where <user> is the user you are trying to log in as, and not only that: the user that partition was created for must have the same user ID as the user trying to log in. The same goes for the default groups. (
/home itself should be owned by root.)
When you create a new user the system will automatically create the correct
/home/<user> directory if you let it. But if you created the new user before the home partition was mounted you won't find it under
/home until you unmount the partition.
I've never seen the error message "Startup Config Doesn't Exist", but there is a
startupconfig in
/home/<user>/.kde4/share/config. If it's missing it will usually be recreated automatically, but I really don't know what would happen if your
/home/<user> isn't owned by the right user.
But this is all speculation; there's still too much we don't know about your system.
Edit: Corrected typo.
