bsdinstall no longer uses BSDINSTALL_DISTDIR?

Hi,

I don't know if this is a bug or feature, but bsdinstall no longer
seems to recognize BSDINSTALL_DISTDIR and tries to download
the tarballs, even when this is set.

This is a bother for snapshots, since the tarballs get replaced
frequently and, for jails, I want the install in the jail to be the
same as the parent system.
