I guess is this package have not been developed?

I think this may be related to seuser roots default contexts in /etc/selinux/targeted/contexts/users/root. It seems theres is not default context defined for xdm_t there > [root@localhost ~]# id > context= root:unconfined_r:unconfined_t: s0-s0:c0-c1023 > > [root@localhost ~]# newrole -r sysadm_r -t sysadm_t > failed to exec shell: permission denied > 2009-09-02 > With regard to mapping root to seuser root i am not sure what you are trying to achieve. i think the root seuser is for MLS usage. But in either way i think if you edit the defaults contexts you should be able to make it work As for the labeling issue: the only sensible explanation i can come up with now is that mytest_t may not be defined a files_type. > > > zheyeung > -- > fedora-selinux-list mailing list > fedora-selinux-list@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/fedora-selinux-list
