}This module also supports the configuration of the parameters it exposes
using Hiera. You can do this by namespacing around grub2. For instance, to
set the value of timeout to 10, you would use something like that in
your Hiera files:
grub2::timeout: 10Module will now take into account whether a system has booted with BIOS or with (U)EFI
and will then place the grub.cfg file in the correct directory.
The efi fact represents whether a system has booted with EFI or BIOS and returns a boolean; true or false depending on the system.
