# Special processing of paths depending on whether --prefix,

# desired is some compatibility with the way previous versions
# of BIND built; they defaulted to /usr/local for most parts of
# the installation, but named.boot/named.conf was in /etc
# and named.pid was in /var/run.
#
# So ... if none of --prefix, --sysconfdir or --localstatedir are
# specified, set things up that way. If --prefix is given, use
# it for sysconfdir and localstatedir the way configure normally
# would. To change the prefix for everything but leave named.conf
# in /etc or named.pid in /var/run, then do this the usual configure way:
# ./configure --prefix=/somewhere --sysconfdir=/etc
# ./configure --prefix=/somewhere --localstatedir=/var
#
# To put named.conf and named.pid in /usr/local with everything else,
# set the prefix explicitly to /usr/local even though that's the default:
# ./configure --prefix=/usr/local
