dnl ------------------------------
dnl Versions of FRR (or Quagga, or Zebra) before ca. 9.2 used sysconfdir and
dnl localstatedir as-is, without appending /frr. The /frr was expected to be
dnl given on ./configure invocations.
dnl
dnl This does not match standard behavior by other packages and makes FRR
dnl specific packaging changes necessary to add these options. localstatedir
dnl was also misused to include the /run part (it normally is only /var),
dnl leaving no path configuration option that references /var itself. This
dnl is because runstatedir did not exist in ancient autoconf.
dnl
dnl The path options have been changed to expect plain / system prefix
dnl directories. As a temporary workaround to not break packaging, eventual
dnl /frr suffixes are stripped and a warning is printed.
