Hmm, sorry.  Didn't know this.

Sounds reasonable.

I didn't try $?, not sure about that.

$^ is a gmake'ism, not present in either BSD or SysV make.

I'd say to wait with this until the split config file approach has been

Yes, -b is documented for BSD install (which is what GNU install features --
SysV install is completely different and IMHO way inferior; i guess auto*
will use something else on SysV).

That's -B in BSD install, but we don't need that.  The default .old should
be OK.
