It's actually a bit more complicated than that.

The system type is a subset of the metadata type, so -m includes -s by 
implication.  Therefore, specifying -d -m is the same as specifying -d -s 
-m, is the same as not specifying any of them.

The normal way to balance system chunks is to balance metadata, which 
includes but is not limited to system chunks.  The -s makes it possible 
to do system chunks only, but to actually make it do it, you will need to 
pass -f, to force the balance, since normally you'd just balance 
metadata, and let system chunks be balanced as part of the metadata 
balance.
