X-Git-Tag: archive/raspbian/2.14_git20250718.0e36779-2+rpi1^2~62
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=d84361010a2823e37d025b2edc652c7f9c065c24;p=grub2.git

"single" -> "recovery" when friendly-recovery is installed

If configured with --enable-ubuntu-recovery, also set nomodeset for
recovery mode, and disable 'set gfxpayload=keep' even if the system
normally supports it.  See
https://launchpad.net/ubuntu/+spec/desktop-o-xorg-tools-and-processes.
