and finally save.
* You can view your change to `systemctl cat grub-btrfs.path`.
* To revert change use `systemctl revert grub-btrfs.path`.
##### Warning:
by default, `grub-mkconfig` command is used.
Might be `grub2-mkconfig` on some systems (Fedora ...).
Edit `GRUB_BTRFS_MKCONFIG` variable in `/etc/default/grub-btrfs/config` file to reflect this.
