 would help :-)

The SuSE support pointed me to the -no-hostonly option that solved my
problem. I really wasn't aware that there are three modes in dracut:
a host-only, a non-host-only and a something-in-between mode. Seems
strange to me. Why does it make sense to create a initrd by default,
that is more generic than a host-only one but not generic enough to run 
on other hosts by missing e.g. modules like lvm or iscsi and by including 
host-only references to the swap device?

At least the man page should be changed because the explanation
of the host-only mode indicates that without this option a generic
initrd is created which is not true.

Frank
