I sent details in private mail. Essentially, empty directories that
exist in the *.tgz file, and that are mentioned in @dirrm lines in
the +CONTENTS file embedded in the tgz, are not created by pkg_add.
Non-empty directories are created almost by accident, as a side-effect
of creating files, with no attention being paid to their ownership or
To fix this, I think pkg_add should parse @dirrm lines, and create each
listed directory with the ownership and permissions described in the
ustar headers in the *.tgz file. Alternatively, we could pass "@option
extract-in-place" to pkg_add, in which case the tar process should
just DTRT with empty directories that exist in the *.tgz file. As yet
another alternative, I suppose we could decree that pkg_add's existing
behaviour is correct, but pkg_create needs to put lines like "@exec
mkdir foo ; chown user:group foo ; chmod 666 foo" into the +CONTENTS

Similarly, pkg_create does not take a -M arg to read a metalog. If it
did, then my patches in PR 22514 could have been simpler.
If somebody taught the pkg_* tools to use pax instead of tar, it would
then become easier to make them read/write a metalog file, and easier
to make them usable as part of a cross build. Oh, we'd probably also
have to teach pax to *write* a metalog file; I think it can only read
metalogs at present.
