Setting Boot Order fail to Mariner OS with UNATTENDED_INSTALLER=y

[mlix666]

Please help me, I have 2 questions now. The first one is to set the remove boot order fail return status 30, refer to picture 1,
and the second one is to annotate the error code and generate a Marine boot order under UEFI that failed to start， refer to picture 2

Compile Command：
make iso REBUILD_TOOLS=y REBUILD_PACKAGES=n CONFIG_FILE=./imageconfigs/full-auto.json UNATTENDED_INSTALLER=y

https://github.com/microsoft/CBL-Mariner/blob/2.0/toolkit/tools/liveinstaller/liveinstaller.go#L178
`
func updateBootOrder(installDetails installationDetails) (err error) {
if installDetails.finalConfig.DefaultSystemConfig.BootType != "efi" {
logger.Log.Info("No BootType of 'efi' detected. Not attempting to set EFI boot order.")
return
}

err = removeOldMarinerBootTargets()                   **## Fail,  return "exit status 30"**
if err != nil {
	return
}

logger.Log.Info("Setting Boot Order")
err = runBootEntryCreationCommand(installDetails)
if err != nil {
	return
}

return

}
`

Error boot log:
