refind-mkdefault \- Set rEFInd as the default EFI boot option

+The script completed successfully, which can mean either that no change was
+necessary or that the call to \fIefibootmgr\fR returned a success code.
+
+.TP
+.B 1
+EFI boot order variables are available, and a rEFInd entry was found, but
+the call to \fIefibootmgr\fR returned a failure code.
+
+.TP

+EFI boot entries are not available. This condition is often an indication of
+a buggy EFI or badly damaged NVRAM contents.
+
+.TP

+No rEFInd entry could be found in the list of boot options, and so
+no changes were made to the boot order list.
+
+.TP
+.B 4
+The script could not run because of OS issues -- the OS was not Linux,
+the \fIefibootmgr\fR utility was not available, or the script was not run
