As the title says. If I run yum update(It's a CentOS box) and there happens to be a Python update. What happens if other users have running Python programs. Do I need to alert them to restart the programs? Or can they safely continue to run those programs basically indefinitely if they like?
To ask differently: Is the old Python version kept on the system(hard drive) for as long there is some process still open. Or does the update immediately overwrite the existing Python installation/binary? So existing processes continue to run only because Python interpreter is completely loaded in memory?
