Hi!

I don't have much clue about all the yast2 stuff -- I'm one from
the backend (wicked + sysconfig) side.... but let's try:

AFAIS, this causes to set DHCLIENT_SET_HOSTNAME="no"

>        <dhcp_resolv config:type="boolean">false</dhcp_resolv>

A "grep -rl dhcp_resolv $(rpm -ql autoyast2-installation)" does not show 
any match.

>        <domain>pnet.ch</domain>
>        <hostname>h063uz</hostname>

-> AFAIS, it causes to write $hostname.$domain into /etc/HOSTNAME

IMO it looks fine with this profile.

This is caused by the yast2 only setting WRITE_HOSTNAME_TO_HOSTS=yes [it 
is never used by anything else] -- default is "no" and it may be
set by some per-product defaults.

Note: it disables dns lookups for the own hostname & ip completely
and may break things.

I'd say, you profile is missing this statement in <dns>:

    <write_hostname config:type="boolean">true</write_hostname>
