>Description:
Checksum in mtree file for /usr/lib/i386/libkadm5srv.so.15.0 differs from that for the file itself in distribution tarballs. See on autobuild cluster, so perhaps MKREPRO issue?

It is only this file that is affected by the cksum problem. This is a long-term problem (also in 9.1 release).

In addition there are two files in the tarball that are not in the mtree:

./usr/lib/i386/libtermcap.so.0.6
./usr/lib/i386/libtermlib.so.0.6

>How-To-Repeat:
Download http://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-9/latest/amd64/binary/sets/base.tar.xz

tar -xpzf base.tar.xz ./etc/mtree/set.base ./usr/lib/i386/libkadm5srv.so.15.0

# cksum -a sha256 ./usr/lib/i386/libkadm5srv.so.15.0
SHA256 (./usr/lib/i386/libkadm5srv.so.15.0) = 20f227ef1fd15342540c2a437795c318ee5a03b42f88fb74f35182cf0ba70ee4

# grep ./usr/lib/i386/libkadm5srv.so.15.0 etc/mtree/set.base
./usr/lib/i386/libkadm5srv.so.15.0 type=file uname=root gname=wheel mode=0444 size=95068 sha256=53144885ce3083af9847f66fbd583fdfb685cf188b7d330df3ce5d3feedd3402

# ls -l ./usr/lib/i386/libkadm5srv.so.15.0
-r--r--r--  1 root  wheel  95068 Apr 28 10:59 ./usr/lib/i386/libkadm5srv.so.15.0

Note that cksums do not match between the file in the tarball and the mtree entry.
