Hi folks,

      I generally speaking don't mind making the Almquist shell into the
      default shell for root in FreeBSD, especially after the many
      commits that have gone into the tree in the last while, which helps
      to make it into a shell that can be used interactively. :)

      As a tcsh user, however, I do feel like I have to point out that
      the way to tell csh apart from other shells is that its default
      unprivileged prompt is % rather than $ - though I see how that's
      not immediately obvious if you don't interact with it except when
      you're root. ;)

      (The reason I'm responding to this mesasge instead of the one that
      oshogbo@ responded to is that that one doesn't appear to have been
      received by my MUA, nor - as far as I can tell - has it been
      received by mlmmj, so I can't even grab the raw file and tell my
      MUA to use it as an mbox, for me to respond to.)
