Subject: [PATCH] Make grub2-switch-to-blscfg to generate debug BLS when
8631a2
 MAKEDEBUG is set
8631a2
8631a2
If MAKEDEBUG=yes in /etc/sysconfig/kernel, then a debug menu entry should
8631a2
be created. So for BLS, a debug configuration file has to be created that
8631a2
contains additional debug kernel command line parameters.
