Hi,
I just ran cvs update (anoncvs.netbsd.org), rm -rf /usr/obj,
build.sh -x distribution, and this is what I get:
checkflist ===> distrib/sets
cd /usr/src/distrib/sets && DESTDIR=/usr/obj/usr/src/destdir.i386
MACHINE=i386 MACHINE_ARCH=i386 CKSUM=/usr/obj/tools/bin/nbcksum
MAKE=/usr/obj/tools/bin/nbmake MTREE=/usr/obj/tools/bin/nbmtree
MKTEMP=/usr/obj/tools/bin/nbmktemp PAX=/usr/obj/tools/bin/nbpax
HOST_SH=sh sh ./checkflist -b
============ 1 extra files ===============
Files in DESTDIR but missing from flist.
File is obsolete or flist is out of date ?
------------------------------------------
./usr/include/sys/tape.h
========= end of 1 extra files ===========
