* Point out, that there is no password feedback for `su`.
* Explain locked (root) account if locked.
* /usr/share/pam-configs/tally2-security-misc

effectively (not directly) add "required pam_tally2.so debug" to /etc/pam.d/common-account
This is required because otherwise something like "sudo bash" would count as a
failed login for pam_tally2 even though it was successful.

set back to default group "root" rather than group "sudo" membership required to use su
since root login will be locked by default anyhow

Thanks to @madaidan for providing the rationale!
