I see alot of ebuild that just go unpack ${A} && cd {S} && epatch .... which is allready partly supported in base_src_unpack but not very nice imo because it doesn't use epatch, and its so hackish to have PATCHES & PATCHES1, and it never even calls 'patch' standard. therefor i prope a change in the order of the patch i'm attaching
Created attachment 34674 [details, diff] base.eclass patch
