Does the su command change my SELinux identity and role?
In previous versions of Fedora Core, security context transitions were integrated into the su via pam_selinux. This turned out to be more trouble than it was worth, and is quite unnecessary on a system running targeted policy. So, this is no longer the case. Now, su/sudo only change the Linux identy. You will need to use newrole to change the SELinux identity, role, or level. Other forms of Linux/UNIX® identity change, for example setuid(2), also do not cause an SELinux identity change.
