I said "single token." I meant as in a single word, not a string of
multiple tokens having its own internal syntax. Heck - if by 'string'
you just mean a sequence of bytes, then I could construe any data
representation as a 'string'.

I don't know if it is a good idea in this case, but each time we add
another pseudo file system interface to the kernel, we should make
an effort to keep the contents of each such pseudo file to a number,
a list of comparable numbers, or a single word.

I'm pretty sure this convention (single number or word per file,
or at most a list of numbers) has been encouraged elsewhere, though
I don't see where offhand.

I do think it is a good idea to be reluctant to introduce new magic
syntax, such as seen in "bind={3/normal 1/high 0/dma}" in kernel-user
interfaces. Though, as I noted in my previous post a few minutes ago,
I sure hope we don't need zones here anyway - just nodes.

I won't rest till it's the best ...
