Earlier as reported "replace seed/sprout hangs (regression ?)" and since now I don't see that regression, was able to test this scenario. And thus added the support in the sysfs. Test case mount seed device add sprout replace seed device (so now sprout fs is independent of seed fs) The sysfs layout should change accordingly.
