When running softupdates, freed disk space is not returned to the free
list for 30-60 seconds. Since install(1) deletes the existing target
files rather than over-writing them, this means that a larger pool of
free space is required when doing installworld with a softupdates
target. With the old 128MB (or less) root partition, there may not
have been sufficient free space so softupdates was disabled by default.
With the new 512MB root or the proposed multi-GB /+/usr+/var there
is unlikely to be a shortage of free space so it would be quite
safe to enable softupdates.
