No problem here, the test would still succeed and return 0. (But I
predict that EROOT containing spaces will cause a lot of trouble
elsewhere. :)

For what, existence? There may well be a "boot" directory present under
EROOT. (And we could check ${EROOT}/etc/fstab, but I don't think we
should open that can of worms. There's no reliable way to guess the
user's exact configuration for non-trivial ROOT.)
