Perhaps it would be a solution to select the 'least value'-partition in 
this case - postulating that
/dev/da1s1 >= /dev/da1s1c >= /dev/da1s1[a-b,d-h] (which is always the 
case). In the moment the opposite is the case and geom_vinum 
opens /dev/da1s1 in that situation :-(

I don't know, if, when opening /dev/da1s1a for writing, GEOM triggers a 
spoil event as well because GEOM *is aware* that da1s1a is in fact the 
same as da1s1c resp. da1s1. Does anybody (Lukas/Pawel/phk) know?
