This page (http://mywiki.wooledge.org/BashFAQ/029) also suggests using
`find -printf %l`. I think it is more about not having a readlink at
all that burned us in the past (the actual BSDs?)

Part of me says this still doesn't feel quite right. What if I just
*move* my repo to repo.db? Is there a way to get bsdtar to use the
same compression as another file, or some trick with file, like what
we do in makepkg (search for 'application/', that will allow us to do
this?
