Re: patch-system hacking

[GSB@MIT-MC]

About the only other thing i found i just had to add was a protocol for
changing the system status out from under a dump.  Essentially, the
dumped maclisp job has to call a function which looks at the patch directory
and re-reads the system status for its exact version number.  This
of course is hidden away in stuff which does jcl parsing and init file
loading;  but it is fairly important if, say, it is discovered that
something is broken after it has been installed.  (Things like load-patches
automatically do this update since they are accessing the patch-directory.)

p.s.  there should be a function to nicely print the out-of-core stuff,
somewhat like print-system-modifications.  I called it print-system-history;
