Dear Debian boot, It is now possible to set up Debian system without a root password. On such system sudo must be used instead of su. What is the canonical way to detect such situation ? My purpose is to change su-to-root to automatically default to sudo mode on such system.
I would use: passwd --status root And look if it is expired, locked, or with an invalid password (RTFM to interpret the output) ciao cate
