OK, maybe it's my noobishment here, but after switching to udisks v1 
instead of v2 the log-outs would only show xbps successfully installed xxx 
package.

No more udisks errors, all errors now come as successful install of xbps 
package which happened earlier during the day via the regular xbps-install 
-Su.

I can see I am talking to myself, does that mean nobody else ever 
experienced such behaviour ?
