Hello,

I’m trying to add some features to an xCAT HPC Cluster but I’m with some issues 
with SSH Host Keys.

My clients are running ipa-client-install on bootime since I’ve already 
deployed an FreeIPA Server on the headnode and I want the nodes to authenticate 
on it.

After some time trying to debug issues I’ve came across to this file. This file 
appears to copy some fixed host keys to compute images. But I’m not sure about 
it.

The point is: what this script really do? Is it really necessary since it’s 
added by default by xCAT. Can it be replaced?

Thanks,
