One day I've decided to have GRUB booting VoidLinux immediately without any timeout. There are a lot of instructions out there in the Internet mostly saying
and you are done. This didn't fork for me.
Going through tens of tutorials, answers, solutions it was difficult to find a reason why GRUB keeps setting hidden menu with
countdown timer set to 3 seconds. I've tried to settup
but with no luck.
Then discovered additional scripts in
/etc/grub.d/ folder (yeah, for me it is not obvious where GRUB's configs and scripts reside). Some folks recommended to comment out
arrange_timeout the option in one of the scripts. However, there wasn't any sign of that. Passing through all that scripts I've found interesting line in the file
if sleep$verbose --interruptible **3**; then
AND THAT WAS IT. Don't know where it came from, maybe it is specific to my installation, but 'thanks' to the line any settings re
timeout=0 were ignored and set actually to 3sec. Changing it to 0 did the trick, thank you GNU god :)
