I only now realized that only mknod existed, up until
a long time, only
later on with the GNU coreutils did mkdir as a command come into
existence.
Huh? See:
https://minnie.tuhs.org//cgi-bin/utree.pl?file=V6/usr/man/man1/mkdir.1
(And probably before that, that was the quickest one to find?)
Maybe that was a typo for 'mkdir as a system call'? (I recall having to do a
fork() to execute 'mkdir', back when.) But 4.2 had mkdir().
