[Qemu-devel] [PATCH 3/6] Fix daemonize options

[Anthony Liguori <aliguori@us.ibm.com>]

The -daemonize option is too restrictive when using with SDL.  It also switches
the working directory to / too early which causes block devices with a relative
path to fail.

The -daemonize option is needed for my regression testing so I've included this
patch in the series.
