Actually no. ;-) The question was, if I can force systemd
not to mount an encrypted partition. I do not have any other
encrypted partitions, so rd.luks=0 is fine.

However, I already found a resolution. "noauto" was missing
in /etc/crypttab from some reason. My fault that I haven't
double checked. Now it works like a charm.

Thank you Kamil for your answers. :-)
