Changing OpenCoreBoot's config.plist to allow to select the default boot disk via AllowSetDefault

[sck]

I've now been able to rebuilt OpenCoreBoot with a new config.plist:

For libguestfs/loop mounting I added these packages to my Dockerfile:

RUN sudo pacman -S --noconfirm linux cpio
RUN sudo pacman -S --noconfirm unzip

OpenCore is missing some files for the image to be rebuilt, so I reinstalled it under /home/arch/OSX-KVM/OpenCore-Catalina

F="OpenCore-0.5.9-DEBUG.zip"

test -f $F || (
  wget https://github.com/acidanthera/OpenCorePkg/releases/download/0.5.9/$F
  unzip -o $F
)

Now the image can be rebuilt without errors:

sudo rm -f OpenCore.qcow2; sudo ./opencore-image-ng.sh  --cfg config.plist --img OpenCore.qcow2

For enabling to boot automatically I removed -device ide-hd,bus=sata.3,drive=InstallMedia and -drive id=InstallMedia,if=none,file=$BASESYSTEM,format=raw from the qemu parameters and used this patch for config.plist:

                        <key>HideAuxiliary</key>
                        <false/>
                        <key>PickerAttributes</key>
-                       <integer>1</integer>
+                       <integer>0</integer>
                        <key>PickerAudioAssist</key>
                        <false/>
                        <key>PickerMode</key>
-                       <string>External</string>
+                       <string>Builtin</string>
                        <key>PollAppleHotKeys</key>
                        <true/>
                        <key>ShowPicker</key>
-                       <true/>
+                       <false/>
                        <key>TakeoffDelay</key>
                        <integer>0</integer>
                        <key>Timeout</key>
                        <key>Timeout</key>
-                       <integer>0</integer>
+                       <integer>5</integer>
                </dict>
                <key>Debug</key>
                <dict>

This will then boot from the first hdd which is where my macos installation resides.

Feel free to use what I documented! I have a slightly different setup atm, so not easy to generate a pull request...

You can try loop mounting the qcow image or just hexedit it and turn that value on.

You’re awesome dude, pull request or can I include this in the code for you?

Any way we can see the code, @sck? Even if it's not in a PR, it would still be useful.
