From Mailman/Makefile.in:

44 MODULES= *.py [...] 64 install: 65 for f in $(MODULES); \ 66 do \ 67 $(INSTALL) -m $(FILEMODE) $$f $(PACKAGEDIR); \ 68 done This means that Mailman/mm_cfg.py is copied over the existing mm_cfg.py when upgrading. I don't think this is intentional, as the next lines in Makefile.in are: 69 $(INSTALL) -m $(FILEMODE) mm_cfg.py $(PACKAGEDIR)/mm_cfg.py.dist 70 if test ! -f $(PACKAGEDIR)/mm_cfg.py; \ 71 then \ 72 $(INSTALL) -m $(FILEMODE) mm_cfg.py $(PACKAGEDIR); \ 73 fi The bug is giving me problems because I'm not compiling Mailman on the same host that's running it, and therefore each upgrade messes up my DEFAULT_HOST_NAME and DEFAULT_URL. The below patch (well, hack really :) should fix this. A cleaner fix would be to rename the distributed "mm_cfg.py.in" into "mm_cfg.py.dist.in" (and thereby avoid the overwriting due to the name not ending in ".py"), but I'll leave the implementation of that to someone else. --- Mailman/Makefile.in.orig Wed Oct 21 21:26:16 1998 +++ Mailman/Makefile.in Wed Oct 21 21:26:37 1998 @@ -64,7 +64,7 @@ install: for f in $(MODULES); \ do \ - $(INSTALL) -m $(FILEMODE) $$f $(PACKAGEDIR); \ + test "$$f" = mm_cfg.py || $(INSTALL) -m $(FILEMODE) $$f $(PACKAGEDIR); \ done $(INSTALL) -m $(FILEMODE) mm_cfg.py $(PACKAGEDIR)/mm_cfg.py.dist if test ! -f $(PACKAGEDIR)/mm_cfg.py; \ -- Harald
