But that means user can not create desired volume during instance set-up.  If we would like
to have, for example, VM with disk offers from 5-100Gb I need to create dozen of same templates
that differ only at root size.

Exactly, there may be more than 1 partion on that 1 drive.. So just increase disk size, and
let administaror handle the "inside VM" job
