Suppose I have an image home.img of a home partition of another linux machine (B). On that machine there is a users userB and there is a special group, groupB. Consider for example a file fileB in the home partition of machine B. Suppose it is owned by userB and groupA.Now if I mount (via mount home.img /mnt/homeB -o ro) the img file on another linux machine A (logged in as userA), fileB is now owned by userA. Is it possible to modify the mount options such that the owner, groups and permissions are shown on machine A, as it would be shown directly on machine B (for example that fileB is owned by userB and not by userA)? Do I have to create a dummy userB and groupB on machine A?
Correct owner, group and permissions when mounting an image file
filesystems;permissions;mount;users
