説明

What are the host-side ids to use when running multipass mount? I am accessing files through a user other than "multipass".

Without specifying -u and -g, I see from "multipass info", the following map: "UID map: -2:default". From the code, it looks like both the host and instance ids should be unsigned integers.

調査方針: Investigate the current implementation of ` uid map` and ` gid map` in the mount command, likely in the source files related to mount handling (e.g., `src/client/cli/cmd/mount.cpp`). Check the existing UID/GID mapping logic and how wildcards could be parsed and applied. Review the 10 comments on this issue for any proposed solutions or further clarification on expected behavior. Ensure that adding wildcard support does not break existing integer based mappings.
