grub2/0098-Add-grub2-switch-to-blscfg.patch
Javier Martinez Canillas e1531466e1
Update to grub 2.04
This change updates grub to the 2.04 release. The new release changed how
grub is built, so the bootstrap and bootstrap.conf files have to be added
to the dist-git. Also, the gitignore file changed so it has to be updated.

Since the patches have been forward ported to 2.04, there's no need for a
logic to maintain a patch with the delta between the release and the grub
master branch. So the release-to-master.patch is dropped and no longer is
updated by the do-rebase script.

Also since gnulib isn't part of the grub repository anymore and cloned by
the boostrap tool, a gnulib tarball is included as other source file and
copied before calling the bootstrap tool. That way grub can be built even
in builders that only have access to the sources lookaside cache.

Resolves: rhbz#1727279

+--grub-directory=\fIDIR\fR
+Search for grub.cfg under \fIDIR\fR. The default value is \fI/boot/efi/EFI/\fBVENDOR\fR on UEFI machines and \fI/boot/grub2\fR elsewhere.
+
+.TP
+--config-file=\fIFILE\fR
+The grub config file to use. The default value is \fI/etc/grub2-efi.cfg\fR on UEFI machines and \fI/etc/grub2.cfg\fR elsewhere. Symbolic links will be followed.
+
+.TP
+--grub-defaults=\fIFILE\fR
+The defaults file for grub-mkconfig. The default value is \fI/etc/default/grub\fR.
+
+.TP
+--bls-directory=\fIDIR\fR
+Create BootLoaderSpec fragments in \fIDIR\fR. The default value is \fI/boot/loader/entries\fR.
+
+.TP
+--backup-suffix=\fSUFFIX\fR
+The suffix to use for saved backup files. The default value is \fI.bak\fR.
