[9fans] fs configuration botch

[erik quanstrom]

in rereading the fs configuration information and
my actual fs configuration i see that i have 
        c[w.0.<0-1>.0]p(h0.0.0)02.98
but i think i wanted
        c[w.0.<0-1>.0]fp(h0.0.0)02.98
with an "f".

is there any way to save this configuration?
that is, does "f" change the disk represnetation or
only the semantics?
