Hmmm... This might actually be considered a bsdtar bug.
I'll look into it.
That behavior of BSD tar(1) surprised me, to be honest.
It's a trivial fix; there's already a check for whether
tar is being run by root. If so, it sets _EXTRACT_OWNER
to restore the owner. I just need to fill in the flags
associated with -p as well.
One problem that I don't see documented in any GNU tar
docs I can find: Is there a way to suppress this behavior
for root in GNU tar?
From tar.info:
%%%
`--no-same-owner'
Do not attempt to restore ownership when extracting. This is the
default behavior for ordinary users, so this option has an effect
only for the superuser.
