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 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
