Is there a way to specify that I want to install (emerge) the latest 3.10.X series of sys-kernel/gentoo-sources as a slot, in parallel with the latest gentoo-sources?
Currently, that would be version 3.10.28. I know I can specify it like so, emerge =sys-kernel/gentoo-sources-3.10.28 but then it would not get "auto-updated" when a newer version of that series (for example 3.10.29) becomes available in portage.
