Subject: Add a patch to 'halt' that will shutdown all the processes within contexts
X-Git-Tag: 4.2-rc3~32
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=2a018def41260698fb3042da2e33ae49efcecdc5;p=build.git

Add a patch to 'halt' that will shutdown all the processes within contexts
before everything else.

This is necessary because without this, a node would try to shutdown but hang
indefinitely with error messages like:

    umount: /vservers/<slicename>/proc : device is busy
    umount2: Device or resource busy

and finally:

    INIT : no more processes left in this runlevel

But not actually reboot.  This patch has worked in an alpha env where the
original halt script had failed.
