installing globally is good (preferred, I'd even say, it's easier to fix security holes in one place only - all these Linux distributions cannot be wrong, right?)... _if_ you can share dependencies with other parts of the system and your system is aware of files you installed (so that it will not try to install libraries you already have or will not install applications that depend on different versions of libraries if these libraries cannot coexist in the same env. (i.e. are conflicting with each other) - like many Python modules) > Once a machine of mine goes production, it never gets updated except for > security releases. just one question: are you 100% sure that none of the tools you use to get/install/be notified about/whatever these security updates is written in Python or has some Python dependencies and Python modules/Eggs you installed are not breaking them? If yes, everything is ok. > If I need to have "another app" with a different version I will use a VM > or a new server. I meant "another app" as in completely not Pylons related. What if you'll install a log parser written in Python that should notify you about problems with this machine and it's not working correctly due to a bug in one of libraries you installed with your application (and which overwrote the working one shipped with your distribution)? -- -=[ Piotr Ożarowski ]=- -=[ http://www.ozarowski.pl ]=-
