(With gtar, though, not with pax; which is why I'm saying that pax is not
Assume you have a PLIST as:
This will result in a binary package tar file as:
Note the absence of paths! Now when you pkg_add this, what actually
- the tar file is extracted to some temporary staging area
- move first bunch into place: passwd -> /etc
- move second bundh into place: ls -> bin
The latter two steps are done in one tar command:
tar cf - passwd ls | tar -xf - -C /etc passwd -C bin ls
note the double use of the -C switch - this is what pax doesn't do.
