Question about .footprint

Can anybody explain why pkgmk replaces the actual kernel version by "<kernel-version>" in footprints (the pipe sed "s|\tlib/modules/`uname -r`/|\tlib/modules/<kernel-version>/|g" in line 199)? It doesn't seem to be used by prt-get or any of the pkg-utils, and it makes .footprint unreliable as a TOC for other purposes. Regards, Bernd -- Bernd Eggink http://sudrala.de
