+The WRT1900AC among other Linksys routers uses a dual-firmware layout.
+The bootloader passes the active rootfs in bootargs and also sets the
+rootfstype to jffs2 - which is clearly something we don't want.
+
+Rename both root= and rootfstype= variables to avoid issues and also
+use the former to dynamically rename the active partition to "ubi".
