For OBS, we're running a full cross-guest inside of a VM. When a build
|
||
|
|
is done there, we reboot the guest as shutdown mechanism.
|
||
|
|
|
||
|
|
Unfortunately, reboot is not implemented in linux-user. So this mechanism
|
||
|
|
fails, spilling unpretty warnings. This patch implements sys_reboot()
|
||
|
|
emulation.
