So, I spent 10 minutes trying to figure out why "userm[tab]" only came
up with usermount. usermod had disappeared from my system! I eventually
figured out that it and all the other account tools have been changed to
mode 750, inaccessible to normal users.

$ /usr/sbin/usermod

As a sudo user, I believe that running admin tools such as usermod as an
unprivileged user to get the help page is a perfectly valid use case,
and this change is a bad idea that should be reversed.
