+# MJW - The new "tar" method of unslinging does not care if the device
+# has already been unslung.  The following test has been removed.
+#
+# Check that we can unsling at all!  An unsling operation creates a new
+# rootfs, but it also marks the flash rootfs (with a flag file such as
+# ".sda1root") so that subsequent boots do not create the "var.state"
+# and "dev.state" mounts.  Without those mounts, though, an attempt to
+# unsling will write a new rootfs on the target with an empty /dev
+# directory, which doesnt' work really well.  So this check is all about
+# making sure that we are in a state in which we are capable of
+# performing the unsling operation.
