We now have: swlab155:/usr/src/linux-2.6.10-gold # grep version.h -rI . | wc -l 2143 swlab155:/usr/src/linux-2.6.10-gold # grep UTS_RELEASE -rIi .| wc -l 47 So it appears that its much simpler to change all users of UTS_RELEASE to use some other file, say local_version.h, and have localversion not affect version.h Opinions? mst
