unprivileged

  1. [SOLVED] can not 'chown' folder or file in unprivileged lxc container proxmox ve 6.2

    Hello, I recently created an lxc container in the proxmox 6.2 gui and installed a freeipa server on it. I used a centos 7 template for this.

  7. permissions in /home messed after adding some idmap

  11. Can I ask an uid range not to be mapped in an unprivileged container

    Hi, I'm running FreeIPA and I would like to use unprivileged containers so I can use Docker in containers. My Proxmox host is joined to IPA, and my containers too. My FreeIPA install uses 1284000000-1284200000 for uids and gids. This breaks with: $ cat /etc/subuid root:100000:65536 $ cat...
