Actually, initramfs moves the /dev hierarchy over to the
new root directory, so the /dev directory is actually not different,
but I guess it could happen that brltty still lives in the old root.

I just checked, tty<n> exists, but vcsa1 is the only device
that exists (because init has not yet started and there are no gettys yet).

So I could rpbobably also just set -W /dev ?
