Enables/Disables automatic boot image memory syncs only.
Doesn't affect other types of sync activity. If set to the
default value enableAutoSync, the Active unit will send the
full current boot image memory to the Standby unit(s) after
any operation that affects the boot image.
This object is not applicable for systems that don't
support automatic boot image memory mirroring.
Setting disableAutoSync is necessary during software upgrades
for the case where the boot image memory space is too small to
simultaneously hold both the old and new images.
