system_u process does not have system_r

system_u process does not have system_r

[dE]

I've mapped user 'de' to system_u --

semanage login -l

Login Name           SELinux User         MLS/MCS Range Service

__default__          unconfined_u         s0-s0:c0.c1023       *
de                   system_u             s0-s0:c0.c1023       *
root                 unconfined_u         s0-s0:c0.c1023       *
system_u             system_u             s0-s0:c0.c1023       *

However the processes do not have system_r role, as a result the type 
value of many context fail to set cause unconfined_r is not allowed to 
have that type.

ps auxZ | grep nano
system_u:unconfined_r:unconfined_t:s0 de   544  0.0  0.3 115024 1568 
pts/1    S+   22:11   0:00 nano
system_u:unconfined_r:unconfined_t:s0 root 611  0.0  0.1 112632 888 
pts/0    S+   22:14   0:00 grep --color=auto nano

Actually unconfined_r role is not allowed for the user --

seinfo -uuser_u -x
    user_u
       default level: s0
       range: s0
       roles:
          object_r
          user_r
