+Subject: [PATCH] Add check_completed_boot command on EFI systems.
+
+check_completed_boot <guid> [<timeout>]
+
+checks for a 1-byte integer in an EFI variable guid:CompletedBoot and sets
+a command-line specified timeout, with a default of 30s, if the variable is
+not equal to 1.  This can be used to enter the grub menus in the event that
+your OS did not correctly boot on the previous boot.  It also unconditionally
+sets the value to 0.
