If I understand correctly this still leaves your default installed 
system with SU+J and if you set the sysctl variable it means okay I am 
prepared for trouble when taking a snapshot of a SU+J filesystem?
Why would I want a sysctl variable that gives me known trouble?
Or have I misread your patch?

When taking a snapshot of a SU+J filesystem we already get the nice not 
supported error instead of getting into trouble.

I think SU+J should not be default unless it works fine with the rest of 
the system as described in the handbook.
