If it is "touch debian/rules", then it will be reread; however it will (try to )patch it over and over again. This works: ,----[ Makefile ] | all: | echo hello | | Makefile: patch-stamp | touch $@ | | patch-stamp: | patch -p0 < Makefile.patch | touch patch-stamp `---- ,----[ Makefile.patch ] | --- Makefile.orig 2005-03-30 20:49:16.000000000 +0200 | +++ Makefile 2005-03-30 20:49:20.000000000 +0200 | @@ -1,5 +1,5 @@ | all: | - echo hello | + echo goodbye | | Makefile: patch-stamp | touch $@ `---- Regards, Frank -- Frank Küster Inst. f.
