The subtle difference here is that there are for now no hardcoded
UIDs/GIDs above 65536 and we can easily establish a convention that
all static allocations should be below 65536.
Starting from 100 is just obviously created a problem for now, and
there is no non-violent solution as not all packages can easily be
converted to use dynamic allocations.
