action #116689

Updated by okurz 4 months ago

## Motivation
In #116539 and #116563 we had the problem that we needed to add a static IPv4 address entry to /etc/hosts for hosts to be able to connect to the salt master when instead we should rely on the FQDN entry, e.g. in /etc/salt/minion which we already configure from salt but this step needs to happen initially before connecting to salt.

## Acceptance criteria
* **AC1:** IPv4 addresses have been replaced with FQDNs in all our salt controlled hosts

## Suggestions
* Add to where the salt master is configured. Currently it says to add the host to /etc/hosts
