Well that's a way of doing it. But it's pretty inconvenient. The shell
lets you edit a FileSystem, XML file in place. Then of course I've got
to test bbx_filesystem.c very rigorously because it must work, it's the
heart of BabyXFS. So by writing the shell, I flush out any problems with
it.

 There's not much difference between them, and the vast majority
of *nix commands aren't part of either shell, or the c shell variants,
but rather just programs that happen to be located via $PATH.

 Indeed.  I've not yet understood the advantages of a purported XML filesystem.
 

You embed the XML in the program as a string, and then mount an internal filesystem over it. So you can use stdio functions on internal data.
