unionfs was never merged to the 3.0 kernel, I re-added it to the development trees for 3.2 and the 3.4 kernel (aufs for the 3.6 tree at the moment). The meta data is carried forward from the older kernels as a placeholder and is documented in the .scc file itself: ----------------------- kconf non-hardware unionfs.cfg # commented pending update to a newer version ported to 2.6.35+ # patch unionfs-2.5.4-integration.patch ----------------------- So to get unionfs in the 3.0 kernel, we'd need a port .. but since we've moved on quite a bit past 3.0, I don't know of any pending ports myself.
