[Gllug] Combining SMB and NFS - was Embedded Linux & 1Gbps?

A hardware-specific filesystem?! Or is this not a proper filesystem (a
spec and/or sample implementation) but a `we sell you a box' sort of
deal? That hardly counts in my book :/

i.e. it inherits all the failures of those protocols? Or does it provide
some layer which maps the object-based data store to something
POSIX-like? (Complete POSIX compatibility would be nice: support for
cross-directory hardlinks and not violating the atomicity guarantees is
a must on any modern distributed FS, I'd say.)

Did it? Lustre grew out of dissatisfaction with Coda (which grew out of
dissatisfaction with AFS)...

Cool! :)
