[Solved] Enable "CONFIG_DEVTMPFS_MOUNT"?

Hello,
just read the announcement on the main page and on the udev readme it says:

The /dev directory needs the 'devtmpfs' filesystem mounted

So does thie mean that setting

CONFIG_DEVTMPFS=y

is not enough and that I should also set

CONFIG_DEVTMPFS_MOUNT=y

? It isn't set in the arch default kernel and I haven't had any issue without it so far, despite reading that it is needed, for example here. So can anybody tell me if I need this option or not and why it works in arch until now without it?

Greetings

//Edit: And could the "bug" described in my last link even affect the latest arch iso, since when I tried booting with it my cd-drive wasn't found and I had to set manually a symlink from /dev/sr0 to the place where the script was looking for it? (I remember that it worked with an older iso without this symlink I assume this was an older udev version prior 166).

//Edit2:
I should read the description more precisely...

This option does not affect initramfs based booting, here the devtmpfs filesystem always needs to be mounted manually after the roots is mounted.

So I assume that an arch script mounts this filesystem (as it is not in the defauls fstab?)
