I completely disagree. I looked at the patch above. I personally don&#x27;t like. mounting efivars rw is akin to mounting boot rw by default.<p>A sane linux distro will mount it ro and switch to rw whenever need. Defaulting to rw efivars is, excuse the language stupid.<p>I&#x27;ve done a fair share of efi debugging even removing some of the variables that the kernel will now protect you from breaking.<p>If the issue is that users should be able to remount efivars as rw whenever needed then that should be addressed, not prevent you from doing stuff to it because there is a rogue init system doing crazy stuff.<p>EDIT: BTW, i don&#x27;t think systemd does anything besides write to the various Boot* variables, but I may be wrong. I don&#x27;t see why that can&#x27;t be addressed with a remount. If you replace the boot.efi you still have to remount the efi partition anyway.<p>While Matthew may be right that there is an issue that needs to be addressed, but in one of his tweets he basically says the kernel should fix it because tooling isn&#x27;t and bioses suck. Well, maybe tooling should be forced to fix it.<p>or from the issue:<p><pre><code>    Matthew-Jemielity commented 24 days ago
    What needs efivars mounted at all anyway? So far I&#x27;ve seen:

    grub
    systemctl --firmware-setup reboot
    efibootmgr
    Since those likely need superuser, couldn&#x27;t they handle (un)mounting it themselves?

    As long as distribution that are aimed at consumers remount it ro and on updating kernels wrap grub with remount this is a complete non-issue.</code></pre>
