Test guard detected pijul mv command fails under latest nest or crates:

$ cd
$ pijul init p1
$ cd p1
$ touch a
$ pijul add a
$ pijul rec -am"."
$ pijul mv a b
Error: No such file or directory (os error 2)
$

I dont remember details if it worked before.

This is surprisingly trickier than it seems, the reason being that there could be errors in the transaction, and no error on the file system (or conversely). It was broken recently by a bad way to fix an error of that form.

Confirmed. Cerberus is happy again.
