>for example, in a system with thousands of users, where each user should be mapped to their own ID in a single mount. Brauner said that user namespaces were originally limited to five mappings, but he raised that limit to 340
Is that in units of users, or in units of ranges? For a container, a single ranged mapping (i.e. something like [131072:196608]->[0:65536]) might be sufficient while expressing much more than 340 individual users.
