Figure 2-14 shows the supported values for the  useTrustedSLAs  tunable. By default, trusted  SLAs are not used for newly run processes. A value of  1  ( vmo -o useTrustedSLAs=1 ) means  that the usage of trusted SLAs is in effect. If the tunable is changed dynamically, future run  times of trusted programs use the new value, but existing programs are unaffected. This  setup ensures, for example, that daemons that are started early in the boot process are also  covered by the protection mechanism. root@roell:/ >vmo -h useTrustedSLAs Help for tunable useTrustedSLAs: Purpose: Specifies whether trusted shared library areas are used. Values: Default: 0 Range: 0, 1, 32, 64 Type: Dynamic Unit: numeric Tuning: 0 means that trusted shared library areas are not used. 1 means that trusted shared library areas are used for trusted programs, that  is, programs that are setuid-root, setgid-system, or setgid-security. You can  also specify 32 or 64 to enable trusted shared library areas for 32-bit trusted  programs only or 64-bit trusted programs only.
