 I've attached a patch that:
  - moves the ftpmotd file to /etc/ftpmotd wich is the correct place
  - does not create the ~ftp/bin directory
  - makes skipping the creation of ~ftp/incoming an option by leaving the
    directory name empty.
  - Added text to the Anon-FTP config prompt that points out the previous change
    and advises the user to add -r to the ftpd command-line options in inetd.conf
  - creates pwd.db instead of passwd in ~ftp/etc
  - does not include group and pwd.db entries that start with - or + incase the
    user is using compat mode for the passwd database
 
 My opinion on other suggestions:
  - ~ftp/pub is still mentioned in the ftpd(8) man page and should therefor be made
  - the ftp/anonymous user does not need to be in the ftpchroot file, it is
    chrooted by default
  - not everyone wants all anon downloads logged so the -S should be up to the user
  - quota for the ftp user is not needed if the ~ftp/ dir is not writeable and the
    ftpd(8) has the -r option set
