+Subject: [PATCH] docs: Stop using polkit / pkexec for grub-boot-success.timer
+ / service
+
+We also want to call grub2-set-bootflag under gdm and pkexec does not
+work under gdm because the gdm user has /sbin/nologin as shell.
+
+So instead we are going to install grub2-set-bootflag as suid root,
+grub2-set-bootflag was written with this usage in mind, so is safe
+to be made suid root.
