This reverts commit 93004a8494,
because it broke Rawhide. It also tries to fixes BLS ostree
detection to work in chroots (e.g. during installation) by also
checking for /ostree/repo.

Subject: [PATCH] EFI: console: Do not set colorstate until the first text
|
|
output
|
|
|
|
GRUB_MOD_INIT(normal) does an unconditional:
|
|
|
|
grub_env_set ("color_normal", "light-gray/black");
|
|
|
|
which triggers a grub_term_setcolorstate() call. The original version
|
|
of the "efi/console: Do not set text-mode until we actually need it" patch:
|
|
https://lists.gnu.org/archive/html/grub-devel/2018-03/msg00125.html
|
|
|
|
Protected against this by caching the requested state in
|
|
grub_console_setcolorstate () and then only applying it when the first
|
|
text output actually happens. During refactoring to move the
|
|
grub_console_setcolorstate () up higher in the grub-core/term/efi/console.c
|
|
file the code to cache the color-state + bail early was accidentally
|
|
dropped.
|
|
|
|
Restore the cache the color-state + bail early behavior from the original.
