Yeah, installkernel fails miserably trying to install something other than
/kernel and /modules(actually /modules will be a flat file rather than a
directory full of kernel modules!) if you specified an empty directory as
$DESTDIR. I remember I wrote a patch to move the installation of a manpage
and a few scripts out of installkernel target(need a rework).

I wrote a simple bourne-shell script


to add missing entries from /usr/src/etc/{master.passwd,group} into
${DESTDIR}/etc using pw(8) and run pwd_mkdb afterwards. It probably
need more sanity checks (e.g. refuse to proceed if it found corrupted
entries, or if a predefined uid/gid is already used in $DESTDIR/etc)
and rewrite(using pw is probably a bit too far). After running this
script in the earlier stage of installworld, you can point the updated
password file via
  install -L $DESTDIR/etc ...
