In the process of creating the +CONTENTS file from the PLIST (in
pkg_create) we calculate MD5 checksums of all files right now, so that may
be a possible point to add that signing.
But!
I think there's a difference if you sign every file in an archive, or the
archive as a whole, and as such I'm not sure this approach is good enough.
I think the -s thing could be automated to just look for a .sig file
besides the .tgz/.tbz file, and do verify when found. Care should be taken
that this does work on local storage as well as via ftp & http (-s
currently does only work for local storage AFAIK).
