How about committing this??

# /usr/src/sbin/sysctl/Makefile

DIR=${.CURDIR}/../../usr.sbin/sysctl

CFLAGS+=-static
NOMAN=yes

.PATH: ${DIR}
.include "${DIR}/Makefile"

(tested, works, used;  patch for /usr/src/sbin/Makefile is obvious)

There are many things which can be done with sysctl and are potentially
useful from single-user... say, if I need special IP options for NFS
mounts, etc.??
# ls -la /sbin/sysctl

Please, anybody who wants to make life easier for diskless boxes, do it!
