Public bug reported: Kernel image linux-image-3.8.0.31-generic Ubuntu 12.04.3 LTS
I'm setting up machines with nfsroot. dhcp works fine, but a static address fails to set resolvconf. The document https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt states that there are between one and nine fields in the kernel command line option 'ip=' separated by colons. The last two are dns0 and dns1 e.g. APPEND root=/dev/nfs nfsroot=10.0.0.1:/exports/nfsroot initrd=boot/initrd.img ip=10.0.0.200:10.0.0.1:10.0.0.1:255.0.0.0:itx1c:eth0:off:10.0.0.1:0.0.0.0 rootwait=1 nfsdebug=1 nfsrootdebug=1 rw I find that if I supply one or both dns addresses, then the boot fails with the message ipconfig: too many options for eth0 and then when configure_networking (from scripts/functions in /usr/share/initramsfs-tools/) runs (called by scripts/nfs) says it can't create it's temp file /tmp/net-eth0:off:10.0.0.1:0.0.0.0 After that we get a kernel panic as init completes badly. Clearly the command line parsing does not meet the spec in the above reference. I'm sure I can work round this by not supplying dns addresses in the command line and re-writing /etc/resolv.conf elsewhere, but this needs fixing properly. I'm not sure if the ip= line is parsed elsewhere so I don't have enough information to offer a proper fix. ** Affects: ubuntu Importance: Undecided Status: New ** Tags: initramfs-tools nfsroot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1251274 Title: Kernel command line does not correctly parse ip field if nfsroot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1251274/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
