I think he's saying that one shouldn't be prohibited by length from
manually typing "setenv nfsboot ..." to set a value that is no longer
than (or even is identical to) the default value.

What is the resource constraint here that prevents accepting longer
console commands?  This is a change to the config for a board that comes
with multiple gigabytes of RAM.  This is not code that runs prior to
relocation.

Whether the environment scripts could, in time, be structured better is
a separate issue from whether there's a good reason to keep this
arbitrary limit at its current value that prevents people from manually
typing in what is currently being used.
