Hi Merlin, if I understand your correct, the resolv.conf inside the nfsroot is always correct.
Upgrading the nfsroot using -kvp did not rebuild the whole nfsroot, it just upgraded it without changing resolv.conf Using fai-make-nfsroot -fvp rebuilds the whole nfsroot. But building the nfsroot just copies the /etc/resolv.conf from the FAI install server into the nfsroot. This should/can not reverse the order of the entries in resolv.conf. When the client does a network installation using PXE it uses the resolv.conf from the config space or from inside the nfsroot. See lib/subroutines line 1066ff We also use lib/create_resolv_conf which copies the resolv.conf from the initrd (created by dracut) or loops through the list defined by $DNSSRVS (which comes from the DHCP server and is created by ./lib/dhclient-perl). The difference between 5.3.6 and 5.8.x may be that we copy the resolv.conf from the config space nowadays. IIRC we did not that before. But I'm not sure. Maybe the order of the nameserver in $DNSSRVS was always reversed but noone had problems with it. So, please check all resolv.conf versions (on the FAI server itself, in the nfsroot, inside the initrd, on the client) and tell which are the wrong version. Maybe change all cp commands of a resolv.conf to cp -v. Also check the order of DNS servers in dhcpd.conf on your dhcp server. -- regards Thomas
