Its there for legacy reasons.

Ideally, nothing "special" should be using the first storedir, like netdb.
(And that fails anyway if you use / and run Squid as non-root, so it should
be changed :)

The swap.state isn't used for the null fs, its never opened, closed or checked.
Its a holdover from way long ago, back in "modio" branch days, when I broke
the storage code out into modules. Every storage module back then had a
path, so I put "path" as being something in the SwapDir struct and parsed before
options were handed off to the per-storedir type parser. Another example of
an annoyingly-chosen line in the sand.
