When From a terminal session I execute shutdown -r now,
I will get a grub menu with a 10 seconds delay
When I Reboot from the Virtualmin screen
the GRUB menu keeps waiting for a user choice
this delay value is probably -1
where can i change the valua so that a virtuamin reboot wiol not wait for user input.
edit the /etc/default/grub file is the wrong answer, I already did that.
changing rthe value from 10 to 20 works also.
That is the strange behavior.
