  60                 <citerefentry><refentrytitle>sethostname</refentrytitle><manvolnum>2</manvolnum></citerefentry>
  61                 system call. It should contain a single
  62                 newline-terminated host name string. The
  63                 host name may be a free-form string up to 64 characters
  64                 in length, however it is recommended that it consists
  65                 only of 7bit ASCII characters and no spaces or dots,
  66                 and limit itself to the format allowed for DNS domain
