I will review. Thank you.

yea, that does not seem very feasible. IMO fixing udisks is the way to go. If
the above linked issue is not relevant, I'll open a new ticket there.

Do you think this bug report should be closed? or would you rather have it open
and blocking on a possible update from udisks?
