Here they are not synchronized. And therefore the problem you show. But if you synchronize them then the problem you describe does not exist. > Now to the issue I mentioned. > The uid for rocketmouse and spinymouse are equal, 1000. Not if you synchronize the uids. Pick one to be 1000. Move the other one to 1001. Then then will be different. Then both systems will have the same list of users and uids. > If you share content from one /home with another /home, e.g. > > /home/spinymouse/.local/share/evolution/mail -> /mnt/archlinux/home/rocketmouse/.local/share/evolution/mail > ^^^^^^^^^^ ^^^^^^^^^^^ > /home/spinymouse/VirtualBox VMs -> /mnt/archlinux/home/rocketmouse/VirtualBox VMs/ > ^^^^^^^^^^ ^^^^^^^^^^^ That is the entire point of why I suggested synchronizing the uid numbers between the systems! Have exactly one uid per name. No more. No less. One only. Two users with the same uid is right out! :-) It is a little bit of work to edit the files to synchronize the uids. But then there is no conflict between the systems. It is easier in the long run. > The user name is important too, not only the uid. This might not be an > issue for the OP, when users should share another folder than home. I think we are talking past each other. If the uids are the same in the two systems then they cannot be different in the two systems. File /etc/passwd on both systems will contain: rocketmouse:x:1000:1000:rocketmouse:/home/rocketmouse:/bin/bash spinymouse:x:1001:1001:rocketmouse:/home/rocketmouse:/bin/bash Or the /etc/passwd file on both systems will contain: rocketmouse:x:1001:1001:rocketmouse:/home/rocketmouse:/bin/bash spinymouse:x:1000:1000:rocketmouse:/home/rocketmouse:/bin/bash Pick one or the other and make it so. Anything else is not synchronized. Bob
