I have connected a host system directory to an lxc container, configured a read/write UID/GID mapping of the user in the connected directory. After starting the container, the permissions on the directory are correct, but all permissions of this user in the container have changed to nobody:nogroup.
How to do UID/GID mapping correctly?
/etc/subuid
root:100000:65536
root:1001:1
/etc/subgid
