hostname lookups resolve to FQDN

[kelbstf]

Hello,
it looks to me like warewulf is creating nodes (when having populated the "eth0.FQDN" field in the node definition via "--fqdn=") that resolve "hostname" lookups to their FQDN, instead of the expected "hostname -s".
This causes problems for NHC when triggered by SLURM:

error: _find_node_record(763): lookup failure for <FQDN>

Is there any option i am not aware of to come up with WareWulf provisioning nodes which resolve "hostname" lookups to "hostname -s" equivalents?

It looks like warewulf3 graps the hostname from the first position in /etc/host, which is the FQDN, when dropping "localdomain" as described.
Extracting the short hostname would resolve the problem.

Currently i have to readjust the hostnames of the deployed compute nodes using a postinstall script, which is not as neat as it could be.

Best
