+Subject: [PATCH 5/5] clearfog: Move all extra bootargs to a special variable
+
+I have two reasons for this, and both of them center around making it
+possible to perform changes to the boot process.
+
+It is quite dangerous to attempt to re-flash the entire card, including
+the bootloader, on the fly. Moving as much bits as possible to the
+environment makes it a bit easier to introduce important changes such
+as, for example, volatile rootfs, later on.
+
+The second one is for testing -- it's much easier to just rewrite one
+reasonable variable. Changes no longer require struggling with overly
+long lines (bootcmd), at least.
