| From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 |
| From: Javier Martinez Canillas <javierm@redhat.com> |
| Date: Wed, 3 Oct 2018 20:48:32 +0200 |
| Subject: [PATCH] add 10_linux_bls grub.d snippet to generate menu entries from |
| BLS files |
| |
| This grub.d snippet can be used on platforms where the bootloader doesn't |
| have BLS support and only can parse a normal grub configuration file. |
| |
| Portions of this script were taken from the ostree-grub-generator script |
| included in the OSTree project. |
| |
| Resolves: rhbz#1636013 |
