Subject: base-files: fix check for empty password warning
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=6c1542787d135de358710254e71fe926f8676954;p=librecmc%2Flibrecmc.git

base-files: fix check for empty password warning

Now that we know that the password is in /etc/shadow and not in
/etc/passwd, we can properly fix the logic for the empty password check.
Only 'root::' is an empty password, 'root:x:' and 'root:!:' allow no
password login at all.

This fixes the empty password warning still showing after the root password
has been locked using 'passwd -l root' (e.g. to allow public-key auth
only).
