How can you make this claim?
Are you ignoring my very simple request that NetBSD tar should be able 
to extract modern archives?

I asked this simple question internally:
"Why does this archive give error on extraction using NetBSD?"

and lo the answer was
"Our tar is too old and not maintained. Does libarchive work?"

And verily I answered
"Yes! It does work? Can we fix the standard tar?"

"NOOOO" cameth the answer.

So, I asked the simple question ......
"Can we change the tar from pax to libarchive?"

And verily no-one had any reason to dispute this ..... until now.

Please do not be blind to my issues either.

From the conversations internally it's basically revert to pax and fuck 
modern archives or add a warning note to upgraders that chroot symlinks 
wont work on upgrading.

I myself have been bitten by this on my ERLITE router.
Real men have backups!
Actually I didn't (lesson learned here) and rc.d/nsd and unbound refused 
to copy over .... so I was able to restore my configs from the chroots.
So here, our rc.d is A WIN FOR UPGRADERS!

Can we not add a note to check links in etc?
