executable ELF is rm-ed from disk, but still running RAM..

Hi all.. As the subject says, I was thinking about that issue. I know that rm-ing a file doesn't delete the data block from the backing device, thus the executable could still survive and running. But logically, we usually expect that once a file is rm-ed, it should also "stop", right? What does POSIX say about this case anyway? Anyone could kindly give his/her opinion? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
