You better don't do that:
when I looked at one of my C8 boxes there were many services that
require a system account (but not a global fixed one) were allocated
from the top of the 500-999 range. Bite the bullet and change user
accounts. to start from 1000. Especially when using NFS this may
otherwise come back and bite you
