+// WARNING: These tests use a fake file system, and any attempt to use a
+// feature that spawns shells will fail, because said shells expect a working
+// directory corresponding to a real directory on disk - see
+// these lines in secretfactory.go:
+//   cmd := exec.CommandContext(ctx, commands[0], commands[1:]...)
+//	 cmd.Dir = f.wd
+// Worse, the fake directory might match a real directory on the your system,
+// making the failure less obvious (and maybe hurting something if your secret
+// generation technique writes data to disk).  So no use of secret generation
+// in these particular tests.
+// To eventually fix this, we could write the data to a real filesystem, and
+// clean up after, or use some other trick compatible with exec.
