Of course you have a way back.

   man vipw

   man 5 passwd

   man 5 shadow

and note the -s option.

   man nologin

   man false

Then

   sudo vipw

and change the line for root (should be the very first line) to give it
either /bin/false or /sbin/nologin as the default shell for root.

(That's the last field.)

   cat /etc/passwd

after you're done, to make sure you saved it. Then,

   sudo vipw -s

and replace the encrypted password (second ffield) there with '*'.

Have you checked group ownership and  permissions?

Also, have you checked your mount parameters?

And have you checked whether you have established SELinux or acl
permissions or anything of that ilk?

(BTW, do you keep a backup of your /home partition? I usually find
myself using cp -p or tar to copy the files from the old /home to the
new one, instead of keeping an old /home around.)

One of these days I'll get someone to pay me
to design a language that combines the best of Forth and C.
Then I'll be able to leap wide instruction sets with a single #ifdef,
run faster than a speeding infinite loop with a #define,
and stop all integer size bugs with my bare cast.
