FYI I just noticed another inconsistency: on my merged /usr systems
(installed as such, not converted later w/ usrmerge), /etc/shells
contains both /bin/ and /usr/bin/ paths for some shells, but not all
(e.g. no /usr/bin/sh, no /bin/screen).

  $ sort /etc/shells
  # /etc/shells: valid login shells
  /bin/bash
  /bin/dash
  /bin/rbash
  /bin/sh
  /usr/bin/bash
  /usr/bin/dash
  /usr/bin/rbash
  /usr/bin/screen
  /usr/bin/tmux
