    v1 v2  
    33> In https://linuxfromscratch.org/blfs/view/svn/postlfs/grub-setup.html (SysV), it mentions adding to the fstab parameters to mount efivarfs at boot. It isn't exactly explained why this should be done. But from what I read, it isn't really necessary. For the Systemd version of BLFS, it says this is done automatically, but it's still important to keep tabs on what's happening.

    5 I can tell you from previous experience that efivarfs needs to be mounted for efibootmgr to be able to modify boot variables. But yes, systemd mounts it automagically at boot. SysV certainly doesn't. For openrc, I cannot tell, but it needs specific code in the `init` binary. Note that when running grub-install in chroot, as said by Xi, efivarfs '''has to''' be mounted.
