Created attachment 4838 [details] Implementation of nologon nologin (8) simply prints a message that a user's account is not available. It can be used for disabled users instead of /bin/false in /etc/passwd. The advantage is that you see a message that a user account is disabled. lp:x:4:7:lp:/var/spool/lpd:/sbin/nologin
Bernhard pointed out there is a shell script in the tree that does this: https://git.busybox.net/busybox/tree/applets_sh/nologin whether we make it a full built-in applet i have no opinion. i'll leave it to Denys.
