如何创建自定义 Snapcraft 频道？

Question

我什至只能在文档中找到几个地方表明这是可能的，但显然是可能的。

Moving a snap between channels helps to manage a user’s expectations in any trade-off between stability in the stable channel, and cutting edge features in the edge channel (as an arbitrary example). But its also a useful technique for beta testing, or for when a snap needs to revert to a previous revision. -- https://snapcraft.io/docs/release-management

以 kubectl（见下文）为例，除了默认的 latest 频道外，每个旧的次要版本都有一个频道。

我们即将发布一个与 Ubuntu 16.04 及更低版本不兼容的新版本，我们希望这些用户可以使用旧版本。我们怎样才能做到这一点？

这些被称为“曲目”。每一个都有自己的边缘、测试、候选和稳定通道。

有一个过程要求您通过 forum.snapcraft.io 话语请求新曲目。有关该过程的更多详细信息，请参阅 https://snapcraft.io/docs/process-for-aliases-auto-connections-and-tracks。
