[CentOS] kickstart storage configuration hangs

While playing with some CS9 kickstart installation attempts (manually/graphical works) I noticed following:

What ever I provide as ks file "anaconda" outputs (text mode):

<snip> Saving storage configuration ... Checking storage configuration ... . . .......................................................... <filling multiple lines>

The ks file has nothing special, the storage related lines are:

ignoredisk --only-use=nvme0n1 zerombr clearpart --all --initlabel --drives=nvme0n1

and then the part/volgroup/logvol lines.

Does someone have the same issue?

I guess anaconda is not ready? Because even the ks file from the manually installed system does not work ...
