Of the shared memory /etc/system tunables the following holds for S10:
- Some have been declared obsolete; they are no longer tunables
and they are now bounded by physical memory
- Some are still used but only to derive the settings for new
kernel resource controls
- All settings remaining are now dynamically tunable and generally
converted to resource controls (this mean they can be set per
project/zone, not just per system)
