[opensuse] dracut emergency shell - where to mount root?
In earlier openSUSE releases, I'm sure I used to mount on /dev/root and then leave the emergency shell with exit or Ctrl-D ? With dracut emergency shell, I have tried /dev/root and /sysroot, both found on the 'net - neither seems to work. I've tried openSUSE 13.2 and Leap both. Background - afaict, dracut or yast does not correctly create an initrd when root is on nfs. For the first boot, I would therefore manually mount root and continue, then correct the initrd. -- Per Jessen, Zürich (-4.1°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

dracut is based on systemd today; which means when it enters emergency mode because some unit fails, when you exit it with ^D it still tries to start the exactly same unit and it will likely to fail at exactly the same place. In particular, if at startup systemd generated "bad" unit, this unit remains - you need to either directly fix generated unit and run "systemctl daemon-reload" or fix the source of generated unit and run "systemctl daemon-reexec" to make it run generators again. What exactly failed? Can you display failed units? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

This is related to the other issue with ip=enp65s1:static etc. Basically the network setup fails, which means the root filesystem can't be mounted. To work around a poorly created initrd, I have usually been able to manually mount root and then continue. In this case I just manually configured the interface, mounted the nfs root, and wanted to continue ... -- Per Jessen, Zürich (-7.1°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
