Go packages in the layer and meta-golang layer
At the moment, this layer brings its own cross Go recipes along with some Go package recipes. This conflicts with meta-golang if one tries to use both. IMO, it would be better to use that layer as a dependency, since it's well-maintained, has recipes for Go itself (and nice golang class to ease cross-compilation of Go recipes) and has some of snapd package dependencies already.
Had this been considered? Are there any plans to do that?
Yes, this was considered but there was no time yet to switch to the go toolchain which is provided by meta-golang. If you want to contribute to get us ported to base things on meta-golang patches are very welcome. Otherwise I will see if I find some time in the coming weeks.
We're coming closer to this. Now that all golang-* recipes are dropped in favor of a vendorized tree for snapd I will look into using meta-golang as a base for the Go compiler next.
Things are changing quite fast and today I think you should target oe-core Go infrastructure. I haven't played with it myself, but as it is something in oe-core it's gonna be way more widely used than separate layer.
