What is /mnt/tonlist? I mean what kind of data is mounted there?

I think we could add support for nfs/cifs and public content to handle these configurations. For now try to execute $ chcon -R -t user_home_t /mnt/tonlist/*
default_t is the label of non standard directories created under /. I believe the file was created in one of these directories and then moved under /mnt. The problem here is whether we allow thumb_t to read any non security file on the system.
I made thumb as userdom_home_reader to see if this is enough. Probably not but we could try it for now.
Comment #8 >$ chcon -R -t user_home_t /mnt/tonlist/* Yes. That works. I can not remember why "system_u:object_r:default_t:s0" is on the data disk /mnt/tonlist. But i changeed it to that at some point in time.
