I think that at the time that was written, mkdir didn't universally
have a "-p" option.  But POSIX has required that for a very long
time, so it's probably safe to assume it now.

A larger issue is that blind "mkdir -p" may not produce the ownerships
and permissions you want for the parent directories.  That's not a
topic to get into in a one-line summary, though.
