17 Yes, this is a weak point of decentralization. We should think how to
18 solve it. The possible solution is using of dependencies between
19 overlays (one overlay says, it depends on other). We already have such a
20 feature, we only need to add more support for it. Example of such a
21 dependency:
23 %cat /var/lib/layman/melpa-stable/metadata/layout.conf
25 repo-name = melpa-stable
27 masters = gnu-elpa gentoo
29 Dependencies on overlays in ebuilds is bad idea I think, as it only will
30 introduce additional problems. Also think what if you need not a
31 package, but an eclass or whatever else.
33 In addition, one question that emerges is possible circular dependencies
34 between overlays. We need a way to handle this.
