I can see a risk that removing purespace will break unexec because of
some oversight of some detail somewhere (simply because it's
a configuration that's basically never tested), but I can't imagine the
breakage to be hard to fix: running without purespace has been used
during the bootstrap for many many years, both with pdump and with
unexec, so it's really not "special".

The only real consequence will be a slightly worse performance, but no
worse than what we get with pdump anyway ;-)
