Description of problem: When virt-rescue exits, it looks for /sbin/reboot and doesn't find it, causing a panic: ><rescue> exit virt-rescue: Syncing the disk now before exiting ... /init: line 120: /sbin/reboot: No such file or directory [ 67.638939] Kernel panic - not syncing: Attempted to kill init!

Version-Release number of selected component (if applicable): 1.7.20 How reproducible: Always. Steps to Reproduce: 1. virt-rescue /dev/null 2. At the ><rescue> prompt type 'exit' Actual results: Error messages above. Expected results: Should reboot cleanly. Additional info:
Fixed upstream. virt-rescue now says: ><rescue> exit virt-rescue: Syncing the disk now before exiting ... [ 5.408459] md: stopping all md devices. [ 6.410490] Restarting system. [ 6.410815] machine restart
This seems to have regressed, using libguestfs-1.10.3-1.fc15.x86_64: $ virt-rescue /dev/null [...] ><rescue> exit virt-rescue: Syncing the disk now before exiting ... /init: line 125: /sbin/reboot: No such file or directory [ 2.314040] Kernel panic - not syncing: Attempted to kill init!

Neither that symlink nor systemctl appear in the rescue environment.
Setting back to ASSIGNED. I had a brief look at this a while back, but I couldn't work out what magic packages needed to be added to get reboot to work. Note that this warning is entirely harmless. The disk is still synced!
I added this patch in 1.11.16: http://git.annexia.org/?p=libguestfs.git;a=commitdiff;h=aa8a9ebf29b7fdc97467e911560a1a7a774e9e1f The output of virt-rescue at exit is now: ----------- virt-rescue: Syncing the disk now before exiting ...

[ 4.011806] machine restart virt-rescue: child process died unexpectedly ----------- The final message is a different issue.
