According to GEOM the .journal volume is a child of the main volume. 
That is, ad4s2d is the parent of ad4s2d.journal.  So hal is reporting 
this correctly (and this is what I see on my home machine which is using 
gjournal).  I'm not sure why you think this is a problem since you mount 
the .journal node in fstab.

As for the mirror problem, I'm not sure how to fix that.  The mirror is 
a child of two nodes which violates the tree structure.  I'm open to 
suggestions or patches.
