I want to mount depending on the cmdline arguments of the kernel.

Basically, what I need is a way to guarantee certain devices/directories to be 
mounted before dracut tries to mount the rootfs.

Also, the mountpoints are inside the initramfs, not inside the rootfs. So 
having them in the rootfs' fstab (when the mountpoints do not exist there), 
seems wrong.

For testing it was extremely helpful that I could provide these devices on the 
cmdline, because the initramfs takes quite a while to build on my machines, so 
replacing a file inside them each time I tried to get the path right would 
have been cumbersome.

I assume there is nothing (yet) that mounts entries before the rootfs gets 
mounted?
