I am about to be lumbered with attaching some IKEA wall cabinets to an
oldish, lath and plaster studwork wall.

I assume they will be supplied with adjustable corner fixings but also
assume these will not co-incide with convenient studs. My thought so far
is to attach a couple of rails and secure to them, closing the
consequent gap with matching trim strip.

However, there may be a better way?
