Whilst trying to get a "make release" to complete using
MAKEOBJDIRPREFIX (so that the src tree remains untouched).

I found that the MINIROOTSIZE=3600 is not enough.  3960 is the minimum
and I used 4200.  I've now found that 1440k is not big enough for
boot.fs does that matter? or do we trim stuff from INSTALL until it
fits?

yes we need to use $DESTDIR/usr/mdec in case we've not yet installed
binstall that supports -b or boot.700000

I assume that's not good :-)
