Tell that to all the people running diskless (and often headless) Linux
boxes as firewalls, routers, IPS/IDS/boundary equipment, public kiosks,
thin clients, etc...

Linux runs just fine, and performs even better in many applications,
when it's not encumbered with the relatively dog slow access times of
physical drives. That's one of the major attractions of Linux in fact.

Ahhhh... Mac OS<10 is pretty basic (dare I say primitive?), and so can
get by without free disk space. But then it's an obsolete OS, so that's
not terribly meaningful. DOS can also run without free disk space.
A modern virtual memory OS needs free disk space to run effectively.

Not too long ago, I got a Linux box to become _very_ unhappy when I
inadvertantly filled up the boot disk to 100%. All sorts of things
started breaking, like 'rm' core-dumping and the like. I assume that was
because the memory manager was trying to grow the swapfile slightly, and
throwing a hissyfit when the write failed.

Since the box in question was an NAS box that I was trying to upgrade
(so that it would usefully talk over AFP to my Mac), the easiest
recovery method was to go into an "Emergency recovery mode" which
booted off a flash chip and replaced the contents of / with the
factory-installed version of the OS. From there, I could (more
carefully) resume my fiddling.

Not to run meaningful workloads with any sort of performance.

I've run numerous Linux distributions off full partitions. Indeed,
that's essentially what a LiveCD is.

Limited special purpose boxes only serve to prove my point.

Baloney.

Thin clients and kiosks are hardly "special purpose boxes" from the
point of view of the guy sitting there using them to begin with, and
your contention was that *any* OS needs disk space to run effectively.
Unless you're ready to embarrass yourself even further by trying to
convince us routers and such aren't effective and don't manage large
amounts of data, your arguments are demolished and you're just engaging
in the time honored tradition of trying to wriggle your way out of
admitting you're FOS. Trying to avoid the inevitable truth that your
alleged learned opinion was nothing more than acute myopia.
