Comment 13 for bug 1978426

I'm attaching a document that details the steps to recreate the behavior in LXC containers, as well as my observations for each of the versions (Bionic, Focal, Jammy). I'll collect a few screenshots of Nautilus that shows what it looks like for each of the versions and add that later.

Even without the screenshots this should be ample information for somebody to investigate in more detail.

There are differences in how gio (and as a result perhaps other applications) interpret the "autofs" filesystem type that is created for autofs mounts. Whereas on Bionic gio doesn't report the autofs mount, it is reported by gio on Focal and Jammy. Thus, when the filesystem is actually mounted, you end up with two mounts reported by gio (albeit each of a slightly different type).

Doesn't look like autofs is doing anything different but what gio reports is definitely different.
