Converting the `ip=dhcp` line to wicked�s configuration format is still not supported by wicked. This is troublesome as it means that wicked needs to probe all interfaces for a valid DHCP offer and -for the sake of NFS root scenarios- chose the first valid offer which includes a root-path option. As said, we currently have no way of representing this in our configuration format but this should be supported in the future.

A workaround would be to use the alternative syntax of `ip=<interface>:dhcp`. But even with the workaround I haven�t been able to make the nfs root use case to work as it just configures the network and stops without attempting to mount the nfs root (seems that the nfsroot.sh is unaware that the network is up?)

Sorry that took a while. Further tests turned out that wicked seems to be confused if both parameters: ifname= and ip= contain the same interface name. So the following command line fails: --> root=nfs4:192.168.57.254:/nfsroot:rw,relatime,vers=4.2,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.57.141,local_lock=none,addr=192.168.57.254 ifname=ens3:52:54:00:dc:43:b6 ip=ens3:dhcp rootfstype=nfs4 rootflags=rw,relatime,vers=4.2,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.57.141,local_lock=none,addr=192.168.57.254 initrd=initrd console=ttyS0 --< removing the 'ifname=ens3:52:54:00:dc:43:b6' parameter results in the following output from 'wicked show-config --ifconfig dracut:cmdline:/home/tblume/Bugs/1180364/cmdline.17357.conf' --> <interface origin="dracut:cmdline"> <name>ens3</name> <ethernet/> <link/> <ipv4> <enabled>true</enabled> <arp-verify>true</arp-verify> </ipv4> ipv4:dhcp <enabled>true</enabled> <update>default-route,dns,nis,ntp,nds,mtu,tz,boot</update> <defer-timeout>15</defer-timeout> <recover-lease>true</recover-lease> <release-lease>false</release-lease> </interface> --< That looks valid. Renaming ip=ens3:dhcp to ip=eth0:dhcp outputs this xml file: --> <interface origin="dracut:cmdline"> <name namespace="ethernet"> <permanent-address>52:54:00:dc:43:b6</permanent-address> </name> <ethernet/> <link/> </interface> <interface origin="dracut:cmdline"> <name>eth0</name> <ethernet/> <link/> <ipv4> <enabled>true</enabled> <arp-verify>true</arp-verify> </ipv4> ipv4:dhcp <enabled>true</enabled> <update>default-route,dns,nis,ntp,nds,mtu,tz,boot</update> <defer-timeout>15</defer-timeout> <recover-lease>true</recover-lease> <release-lease>false</release-lease> </interface> --< which also looks ok for eth0. Removing ip=ens3 instead results in this most probably invalid config: --> <interface origin="dracut:cmdline"> <name namespace="ethernet"> <permanent-address>52:54:00:dc:43:b6</permanent-address> </name> <ethernet/> <link/> </interface> --< So, maybe wicked just needs to ignore the ifname parameter (at least the name from there)? It doesn't seem to be necessary. -- You are receiving this mail because: You are on the CC list for the bug.
