IIRC, we saw discussions elsewhere, and ... I think it's called fedup
(great name, great marketing!) that updated a full release, and it
*really* needed > 500M, as it was dumping a *lot* in /boot. And, as they
say, disk space is cheap, esp. when we buy multiterabyte disks, even for
the root drive. (Ok, most of them are 1TB).
