Nothinfg specal.
It is a partion where I keep data, for exaple docoments and music.
I is mouted with fstab

*** Bug 807058 has been marked as a duplicate of this bug. *** *** Bug 807060 has been marked as a duplicate of this bug. *** 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. selinux-policy-3.10.0-110.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/selinux-policy-3.10.0-110.fc17 selinux-policy-3.10.0-110.fc17 has been pushed to the Fedora 17 stable repository.
