Subject: Add configure option to use vt.handoff=7
X-Git-Tag: archive/raspbian/2.14_git20250718.0e36779-2+rpi1^2~54
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=e80f716593facd4c0598bd03311cbf4d15f74b03;p=grub2.git

Add configure option to use vt.handoff=7

This is used for non-recovery Linux entries only; it enables
flicker-free booting if gfxpayload=keep is in use and a suitable kernel
is present.
