Ah right, good point, thanks.

It doesn't. It fails because the buffer runs out of memory (initialized
to PATH_MAX). Symlinking legacy-340xx to itself leads to a quite
hilarious result:

I'll add this to my email to upstream's list.

Also it's not even really DFS or BFS, since it's at the mercy of what
the OS returns in the readdir() syscall. One more reason to check all
files in the current directory before moving to subdirectories IMHO.

Kind regards,
Luca Boccassi
