10 [ARGS]...]

13 Run a new shell in a new context. The new context is derived from the
14 old context in which newrole is originally executed. If the -r or
15 --role option is specified, then the new context will have the role
16 specified by ROLE. If the -t or --type option is specified, then the
17 new context will have the type (domain) specified by TYPE. If a role
18 is specified, but no type is specified, the default type is derived
19 from the specified role. If the -l or --level option is specified,
20 then the new context will have the sensitivity level specified by
21 LEVEL. If LEVEL is a range, the new context will have the sensitivity
22 level and clearance specified by that range.
23 Additional arguments ARGS may be provided after a -- option, in which
25 case they are supplied to the new shell. In particular, an argument of
26 -- -c will cause the next argument to be treated as a command by most
27 command interpreters.
28 If a command argument is specified to newrole and the command name is
30 found in /etc/selinux/newrole_pam.conf, then the pam service name
31 listed in that file for the command will be used rather than the normal
32 newrole pam configuration. This allows for per-command pam configura‐
33 tion when invoked via newrole, e.g. to skip the interactive re-authen‐
34 tication phase.
35 The new shell will be the shell specified in the user's entry in the
37 /etc/passwd file.
38 The -V or --version shows the current version of newrole

42 Changing role:
43 # id -Z
44 staff_u:staff_r:staff_t:SystemLow-SystemHigh
45 # newrole -r sysadm_r
46 # id -Z
47 staff_u:sysadm_r:sysadm_t:SystemLow-SystemHigh
48 Changing sensitivity only:
50 # id -Z
51 staff_u:sysadm_r:sysadm_t:Unclassified-SystemHigh
52 # newrole -l Secret
53 # id -Z
54 staff_u:sysadm_r:sysadm_t:Secret-SystemHigh
55 Changing sensitivity and clearance:
58 # id -Z
59 staff_u:sysadm_r:sysadm_t:Unclassified-SystemHigh
60 # newrole -l Secret-Secret
61 # id -Z
62 staff_u:sysadm_r:sysadm_t:Secret
63 Running a program in a given role or level:
66 # newrole -r sysadm_r -- -c "/path/to/app arg1 arg2..."
67 # newrole -l Secret -- -c "/path/to/app arg1 arg2..."

72 /etc/shadow - encrypted passwords and age information
73 /etc/selinux/<policy>/contexts/default_type - default types for roles
74 /etc/selinux/<policy>/contexts/securetty_types - securetty types for
75 level changes

77 rate pam service names
