Ignore UIDs as an implementation detail of the local OS, and use situation-specific logic to Do The Right Thing. For example, if I copy/restore my /home directory on a remote server and then sync it back to a new install, and the current UID happens to be different because Fedora changes UIDs to start with 700 in Fedora 10 because we need more for system services, the clearly right thing here is to just change the UID of all the files downloaded to 700, not keep 500 and fail. If you frame the problem too generally, then yes, it becomes impossible to solve. But for most of them, I think the right answer is to not try to push all logic into the OS (filesystem/kernel/libc), but apply situation-specific logic to do the right thing. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
