Unless you have taken very special steps to avoid it, you will
always have a dynamic /dev. This has been the case for many
many years now. udev uses a tmpfs mounted on /dev (and more
recently a devtmpfs mounted on /dev).
If there's nothing mounted on /dev, then you will have a static
/dev. However, if using Linux, the chances of having a static
/dev on a contemporary system are vanishingly small--you'd have
to intentionally alter the boot scripts to avoid a dynamic /dev.
