Description of problem: I am seeing a problem with network name lookup. NetworkManager nukes /etc/resolv.conf because there are no DNS1 or DNS2 entries in ifcfg-eth* entries created by dracut. Version-Release number of selected component (if applicable): dracut-018-23.git20120419.fc17.noarch.rpm How reproducible: Very. Steps to Reproduce: The system was booted with the following line: boot: linux ip=9.5.250.145::9.5.250.1:255.255.255.0:sharpie.rchland.ibm.com:eth0:none ip=9.5.252.203::9.5.252.1:255.255.255.0::eth1:none nameserver=9.10.244.100 bootdev=eth0 When I access a bash shell on the booted system, this is what I see: [anaconda root@sharpie /]# ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 9.5.250.145 netmask 255.255.255.0 broadcast 9.5.250.255 ether 2a:0f:41:b7:3f:03 txqueuelen 1000 (Ethernet) RX packets 1781 bytes 135886 (132.7 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 12 bytes 1072 (1.0 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 19 eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 9.5.252.203 netmask 255.255.255.0 broadcast 9.5.252.255 ether 2a:0f:41:b7:3f:06 txqueuelen 1000 (Ethernet) RX packets 1772 bytes 130305 (127.2 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 1 bytes 90 (90.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 22 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 16436 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 0 (Local Loopback) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 [anaconda root@sharpie /]# nslookup sharpie.rchland.ibm.com ;; connection timed out; trying next origin ;; connection timed out; no servers could be reached [anaconda root@sharpie /]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # Generated by dracut initrd DEVICE=eth0 ONBOOT=yes NETBOOT=yes UUID=44b2d13b-f3ff-4a89-bc76-db7c90447666 BOOTPROTO=none IPADDR=9.5.250.145 NETMASK=255.255.255.0 GATEWAY=9.5.250.1 HWADDR=2a:0f:41:b7:3f:03 TYPE=Ethernet NAME="Boot Disk" [anaconda root@sharpie /]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 # Generated by dracut initrd DEVICE=eth1 ONBOOT=yes NETBOOT=yes UUID=d1fe600f-8a3c-4431-9612-0f620aaa9734 BOOTPROTO=none IPADDR=9.5.252.203 NETMASK=255.255.255.0 GATEWAY=9.5.252.1 HWADDR=2a:0f:41:b7:3f:06 TYPE=Ethernet NAME="Boot Disk" [anaconda root@sharpie /]# cat /etc/resolv.conf # Generated by NetworkManager # No nameservers found; try putting DNS servers into your # ifcfg files in /etc/sysconfig/network-scripts like so: # # DNS1=xxx.xxx.xxx.xxx # DNS2=xxx.xxx.xxx.xxx # DOMAIN=lab.foo.com bar.foo.com
If I break into dracut with rd.break=cmdline cmdline:/# vi /run/initramfs/usr/lib/dracut/hooks/pre-pivot/85write-ifcfg.sh ... namesrv=$(getargs nameserver) if [ -n "$namesrv" ] ; then declare -i i=1 for s in $namesrv; do echo "DNS$i=$s" i=$(($i+1)) done fi ... cmdline:/# exit Then that fixes the problem.
