Thank you. I'll try to play with File and Tree now. btw, I had some problems on /tmp due to free space, getting messages from ./INSTALL as these: ... copy.o: No space left on device /tmp/cc2IGQH6.s: Assembler messages: /tmp/cc2IGQH6.s:3059: FATAL: Can't write copy.o: Invalid argument mk: 9c copy.c : exit status=exit(1) mk: for i in ... : exit status=exit(1) mk: for i in ... : exit status=exit(1) ...
nevertheless, the INSTALL script returned errorlevel 0. I don't think this bothers many people, but I wasn't watching the command output, and I trusted the errorlevel.
