Turns out, the suggested --setactivationskip option is not present in Utopic, as Utopic comes with an LVM version which dates back to 2012 (2.02.98(2) (2012-10-15)), while the feature was implemented in 2013.
Vivid will come with a newer LVM: 2.02.111(2) (2014-09-01).
Activation skip could be a nice workaround if it would be backported.
