It probably does need noting somewhere - I've been doing exactly this for the last year or so and never even thought that I might be risking bad uid/gid values. It makes sense now I think about it but it never crossed my mind. Looking at 'man tar', there is a '--numeric-owner' option to always use numbers for user/group names. It might just be that we need to recommend using this option when untarring a rootfs onto a mounted volume. This option is present in GNU tar, I'm not sure about other implementations, and I haven't given it a proper test, but it looks like the thing we want.
