   | i know of at least one person who built netbsd-8 on netbsd-4.

   | netbsd-6 belongs for now.
 
 Anyone attempting to do a build using obj directories from that
 long ago really needs a different kind of support...
 
 All UPDATING really does (mostly) is tell people when they need
 a clean build because something won't work with existing obj
 directories (which is arguably a build system bug .... but not one
 worth worrying too much about most times).
 
 The (very few) entries that relate to changing config files in some
 way could just be left - but even those get a bit stale over time.
 And even there, no-one bothers with entries in UPDATING when
 the kernel config files need updating, and that's the most common
 requirement (if whoever built 8 on 4 has private kernel configs
 and tried using those unchanged they would have been in for a
 shock).
 
 But for the obj directory removal entries, all that should be needed,
 if it really needs saying at all, is that if your last build was more than
 a year or so ago, delete the whole obj & tools directories, and build
 them again.
