запустить оболочку с новой ролью SELinux (run a shell with a new SELinux role)
Имя (Name)
newrole - run a shell with a new SELinux role
Синопсис (Synopsis)
newrole [-r|--role] ROLE [-t|--type] TYPE [-l|--level]
[-p|--preserve-environment] LEVEL [-- [ARGS]...]
Описание (Description)
Run a new shell in a new context. The new context is derived
from the old context in which newrole is originally executed. If
the -r or --role option is specified, then the new context will
have the role specified by ROLE. If the -t or --type option is
specified, then the new context will have the type (domain)
specified by TYPE. If a role is specified, but no type is
specified, the default type is derived from the specified role.
If the -l or --level option is specified, then the new context
will have the sensitivity level specified by LEVEL. If LEVEL is
a range, the new context will have the sensitivity level and
clearance specified by that range. If the -p or --preserve-
environment option is specified, the shell with the new SELinux
context will preserve environment variables, otherwise a new
minimal environment is created.
Additional arguments ARGS may be provided after a -- option, in
which case they are supplied to the new shell. In particular, an
argument of -- -c will cause the next argument to be treated as a
command by most command interpreters.
If a command argument is specified to newrole and the command
name is found in /etc/selinux/newrole_pam.conf, then the pam
service name listed in that file for the command will be used
rather than the normal newrole pam configuration. This allows
for per-command pam configuration when invoked via newrole, e.g.
to skip the interactive re-authentication phase.
The new shell will be the shell specified in the user's entry in
the /etc/passwd file.
The -V or --version shows the current version of newrole

Changing sensitivity only:
# id -Z
staff_u:sysadm_r:sysadm_t:Unclassified-SystemHigh
# newrole -l Secret
# id -Z
staff_u:sysadm_r:sysadm_t:Secret-SystemHigh
