table the symbol offset address table the symbol accessor code sections as well as the patch library are replaced when the updated patch manager code section 450 is installed the arrangement of the new read write data the new code section address table the new symbol offset address table the new symbol accessor code and the new patch library as the updated patch manager code section 450 together with the current code sections in the code storage section forms updated executable system software when the file system section 110 receives an updated symbol accessor code address the patch manager replaces the symbol accessor code address in the first location in memory with updated symbol accessor code address as noted above the first location in memory 334 is typically in the patch manager code section see fig3 as seen in fig3 the patch library 308 is also includes a compactor or a compactor symbol library 342 the compactor 342 can also be enabled as a distinct and independent code section however as noted above it is useful and efficient to bundle the functions associated with system software upgrades into a single patch manager code section generally the compactor 342 can be said to resize code sections so that new sections can be arranged with current code sections in the code storage section 112 contrasting fig3 and 4 the file system section 110 receives a compaction instruction set with instructions for identifying.
