Sure.  Easiest to demonstrate how this is done with an example I guess --

If you currently run configure with something like the following
./configure --sysconfdir=/etc --with-afs-sysname=i386_linux24 ...

then, eg, viceetcdir is set to /etc/openafs throughout all of the
makefiles.  With the patch, it is set to ${sysconfdir}/openafs which is
literally what is wanted because it allows you to do things like

make sysconfdir=$buildroot/etc install

and have viceetcdir be $buildroot/etc/openafs during the make install as
opposed to /etc/openafs.

This makes OpenAFS act more like most things which use autoconf/automake
in following relocations transparently during the install process.  It
also allows the use of the stock %configure and %makeinstall macros
built into RPM.

Cheers,
