Let me sync with Robert (on Cc) who has been doing the integration to
see what he thinks about that.

We consider the script to be a temporary mechanism. Now that the symlink
support has been added to debugfs, we are working to validate that
everything works via the script. Once complete, the second stage of this
effort is to move some of the logic from debugfs into libe2fs and make
it available to mke2fs as well as debugfs. Then we would want to add the
-i (initial dir) argument I had proposed originally to be able to format
and populate an image in a single step.

I provide that context in case it impacts Mike's plans. Always good to
know what others are planning :-)
