After discussion with Vladimir on IRC, I've brought his efigfx branch
(sftp://bzr.sv.gnu.org/srv/bzr/grub/branches/efigfx/) up to date with
trunk and added some more features to it. It now seems pretty good and
I think it's ready to be merged. Could others review it and let us know
what you think?
Here's a ChangeLog fragment for the parts I was responsible for.
Vladimir said that he would write a ChangeLog for the parts he wrote
(i.e. most of the branch ...). Following that is a diff of the branch
against trunk.
2010-06-17 Colin Watson <cjwat...@ubuntu.com>
* util/grub-mkconfig.in: Capitalise and export GRUB_PREFIX. Stop
setting GRUB_VIDEO_BACKEND. Make it available as a user override
instead. Replace the gfxterm backend check with a check that
${GRUB_PREFIX}/video.lst is non-empty.
* util/grub.d/00_header.in: Use GRUB_PREFIX rather than computing it
again.
(load_video): New generated function. Call it before loading
gfxterm rather than loading ${GRUB_VIDEO_BACKEND}.
* util/grub.d/10_linux.in (linux_entry): Call load_video.
* util/grub.d/30_os-prober.in (osx_entry): Likewise.
* docs/grub.texi (Simple configuration): Document
GRUB_VIDEO_BACKEND.
