Firstly i am sorry for mistake : i run whonix 11 and not 12 .
So shared folder works because i disable selinux on fedora host,
the ''welcome to emergency mode'' message show after edit fstab for automount shared folder , after press ctrl+d the booting continue successfuly but in emergency mode, this is bad ? that connected with apparmor , so there is something critical when we speak for security?
Its better to mount evry time when boot the guest the shared folder and NOT edit fstab for automount?
