I haven't taken any steps at all to verify this, but just looking at
the error message it would appear that it's ignoring sys, which is a
symlink to usr/src/sys. I wonder if it's encountering sys, trying to
create the soft link and finding that usr/src/sys doesn't exist to be
linked to because it hasn't been unpacked yet? That may be the meaning
of the message about an out-of-order file.

If it is indeed sys that's not being created, it's a symlink to a
directory rather than a file or link to a file. If the root of the CD
doesn't contain a directory called sys which softlinks to usr/src/sys,
it should be possible to correct the error by doing
ln -s usr/src/sys sys
in the root of the unpacked CD filesystem.

I may have missed your deadline in that case - sorry, I've been on
