[libvirt] [PATCH RESEND] tools: Only install guests init script if --with-init=script=redhat
Cole Robinson

Sun Dec 9 03:23:57 UTC 2012
Most of this deals with moving the libvirt-guests.sh script which
does all the work to /usr/libexec, so it can be shared by both
systemd and traditional init. Previously systemd depended on
the script being in /etc/init.d
Required to fix https://bugzilla.redhat.com/show_bug.cgi?id=789747

Only change to the big script is dropping the LSB header
