I totally support yamt's patch ... mandating -s is a reasonable
how does one have a default /tmp tmpfs for a fresh install?
i talked to some folks familiar with linux tmpfs. unless a
size is specified, it uses half of ram. i guess in this case
it's like passing -s but is dynamically calculated.
(linux tmpfs also uses virtually no extra ram due to using
other kernel cache objects (ie, vnode/inode/directory) rather
than keeping track of them with private structure. i wonder
if those ideas could be adapted for our tmpfs?)
