I have found out that disabling the change by turning /bin/hostnamectl

I wonder if either change of the --hostname semantics, or some new
option would be useful, to specify the hostname to be used by the
FreeIPA software while not touching the configuration of the hostname

I agree that --hostname options should not touch system's hostname, I
don't see reason why application installer should change system hostname.
It was done for sanity because a staggering number of users it seems
don't properly set their hostname.
Then we should have checks and prevent installation, but this needs
proper design and must cover containers, AWS, etc. to count with various

True, so as mentioned later, rather just deprecate this option.
As you mentioned we need find what cases can be broken when we will use
different local and external hostname, but anyway we have do this for
Agreed. Something needs to happen, I'm just not convinced it should
happen in --hostname. I generally oppose new options but one might be
warranted in this case to handle things.
Maybe --external-hostname or so, noted, we will cover it in design.
