In case of iscsi boot, kernel cmdline will contain ip=xxx kernel parameter for dracut setting up iscsi root in initramfs. For example: "root=xxx ip=192.168.3.26:::255.255.255.0:localhost.localdomain:eno19:none ..." dracut doesn't allow duplicate ip conf for the same network card. dracut will not ignore the either of the duplicate. Instead, it refuses to continue: [ 15.876306] dracut: FATAL: For argument 'ip=192.168.3.26:::255.255.255.0:localhost.localdomain:eno19:none'\n Duplication configurations for 'eno19' [ 16.055513] dracut: Refusing to continue ev argument for multiple ip= lines That's why in our code we don't add a duplicate ip conf when handling the same network card the second time. But we never consider the case that ip conf is already added in kernel cmdline for some special purpose, for example, iscsi boot. Now we also look up /proc/cmdline for ip conf. If it exists, we use the existing one. The existing one should work out of box because dracut will handle it in second kernel like it does for first kernel. That said, the network card will be brought up and root disk will be mounted under /sysroot. Signed-off-by: WANG Chao <chaowang@redhat.com> Acked-by: Vivek Goyal <vgoyal@redhat.com>
