- Replace bind-mounts on /lmn/media/$USER with separate mounting for Home and Share SMB shares in the VM. - Update vm-run to start virtiofsd with /lmn/media/$USER (/home/$USER on localhome machines). - Use vm-vminfo to generate a JSON file containing user information, including Username, Groups, printer list krb5-ticket and some more - Configure vminfo.service (systemd-timer) to periodically call vm-vminfo. - Ensure krb5-ticket (TGT) is injected into the Windows VM. - Mount SMB-Home and SMB-Share shares as part of the new structure.
