Comment 4 for bug 236975

Thank you for the update.

If I'm not wrong, this would make it easier for end-users to "tweak" permissions if you don't put a password on the grub menu entries (which you should do anyway, as otherwise unprivileged users could be dropped to a root shell)

I know it's a bit of security-through-obscurity and is certainly less flexible, but I think it might be safer to have the desired permissions hard-coded in the initramfs. Perhaps I'm worng/misguided. Wouldn't be the first time.

Anyway, either way it does the job. It'd be just fantastic if there was a nice little GUI that would do this for you (or at least documentation, which I guess is what this is now.) Alas, I'm not volunteering to do it. This workaround was my best effort.
