    [SOLVED] Cat get any gid mapping to work

    Do idmaps for bind mounts in multiple unprivileged containers require separate users?

    Hi folks, I have been using the unprivileged containers wiki guide to bind mount a directory for containerA (uid+guid 1000), which works grand. When I tried to do a similar thing for a separate mount point for containerB (also uid+gid 1000), things went awry. Using the same idmap lxc config...

    lxc.idmap differing from 100000

    Hi, for better auditing what's happening in our containers I'd like to change their idmaps to distinct values. Besides their filesystems, is there something I'd need to consider doing so? Will it break PVE and result in a flaming pile of hardware? Bests, Masin

    permissions in /home messed after adding some idmap

    Hello, I'd like to setup unprivileged containers with glusterfs mount in it. The idea is to have 1 ansible controller in each datacenter, so, in case we lost a datacenter connectivity, we still be able to run playbooks from the other datacenter. So, my lxc.idmap does the job for the bind mount...

    Restoring a unprivileged container with custom idmap results in nouser/nobody folders

    Hi, I created a unprivileged container and created a user with ID 1003 (user1) in it. I wanted to map that user to a user with ID 200001 (user1) from the Host system, so I can attach a external hard drive and map it inside the container and administrate it from the Host with a meaningful user...
