I assume that you're talking about "Service bus API," although that is covered by the interface stability promise, so I'm not sure. Not that it matters though -- everything with type DBus is covered by the promise.

If you're instead referring to "reimplementable independently," I think you misunderstand what that is supposed to mean. Those interfaces are considered too specific to systemd and other systems should implement their own specific interfaces. Therefore, the systemd developers don't want to provide counsel for reimplementations. Nonetheless, the interfaces are stable, and the developers won't stop you.

No, not every D-Bus API is covered. The article you provided says as much--the D-Bus interfaces of the main service daemon are explicitly listed under the APIs that are NOT covered.

The same article says that these interfaces will eventually be stabilized. Presumably, so that development in the various systemd components can occur without breaking other components' functionality.

I would never expect it from them.

Are we looking at the same web page? I don't see anything with type DBus (column 2) and covered by interface stability promise "no" (column 3). Perhaps you can provide the examples I'm not seeing.

Even if we include non-DBus interfaces, every interface except "udev session switch ACL properties" is included in the interface stability promise.

Ah, I think we're looking at different articles (but on the same subject). You're looking at this one [1], right?

The one I was referring to was peter-b's article [2]. This one's the one that says that the D-Bus interfaces to the main daemon are not stable.

My apologies for the confusion.
