Run COMMAND with completely-specified CONTEXT, or with current or
transitioned security context modified by one or more of LEVEL,
ROLE, TYPE, and USER.
-c
compute process transition before modifying context
-t
change current type to the specified type
-l
change current level range to the specified range
-r
change current role to the specified role
-u
change current user to the specified user
--
The -- flag indicates that runcon should stop processing command
line arguments. Further arguments will be passed to COMMAND.
If none of -c, -t, -u, -r, or -l, is specified,
the first argument is used as the complete context.
Note that only carefully-chosen contexts are likely to successfully
run.
