Hi,
On my Fedora 20 system, I list roles and I can see:
semanage user -l
Labeling MLS/ MLS/ SELinux User Prefix MCS Level MCS Range SELinux Roles
guest_u user s0 s0 guest_r root user s0 s0-s0:c0.c1023 staff_r sysadm_r system_r unconfined_r staff_u user s0 s0-s0:c0.c1023 staff_r sysadm_r system_r unconfined_r sysadm_u user s0 s0-s0:c0.c1023 sysadm_r system_u user s0 s0-s0:c0.c1023 system_r unconfined_r unconfined_u user s0 s0-s0:c0.c1023 system_r unconfined_r user_u user s0 s0 user_r xguest_u user s0 s0 xguest_r
However http://www.selinuxproject.org/page/RefpolicyBasicRoleCreation lists roles such as logadm_r etc. Is there a reason these are not in f20?
