Thanks - I thought just running 'menuconfig' would allow me to enable it (for a quick test).

However, this still doesn't seem to be working. I can see that 'my_cedartrail.scc' gets fetched in to the build area, but I still don't see CONFIG_UNION_FS if I run 'menuconfig'. There is also no 'unionfs' folder in fs/ of the build tree.

Also, if I specify an invalid feature (e.g. feature2/unionfs/unionfs.scc) I'm not seeing any diagnostic.
