if you are on unix and don't *ever* intend to go to plan 9, reduce to
npfs, spfs, ixp

if you don't need threads, reduce to spfs, ixp

libspfs lets you do stuff like this (from xbootfs)
static void
fsinit(void)
{
        Spfile *file;
        root = spfile_alloc(NULL, "", 0555 | Dmdir, Qroot, &root_ops, NULL);
        root->parent = root;
        spfile_incref(root);
        root->atime = root->mtime = time(NULL);
        root->uid = root->muid = user;
        root->gid = user->dfltgroup;

        create_file(root, "ctl", 0644, Qctl, &ctl_ops, NULL, NULL);
        datafile = create_file(root, "data", 0444, Qdata, &data_ops,
NULL, NULL);
        datafile->length = filelen;
        create_file(root, "avail", 0666, Qavail, &avail_ops, NULL, NULL);
        file = create_file(root, "redir", 0444, Qredir, &redir_ops, NULL, NULL);
        /* make it too long, it matters not ... */
        file->length = 32;
}

if you don't need stuff like that, use libixp

or, if you want to read a nice, tight implementation of 9p in c, just
get libixp anyway. It's neat.
