Re: [9fans] Namespace inheritance between processes

Thanks Skip and Anthony for the scripts! Okay, that makes sense. What is the reason for performing namespace inheritance by copy as opposed to namespace inheritance by reference? Is it just to simplify the implementation? It seems like it might be useful. For example, if you had a daemon that

Re: [9fans] Namespace inheritance between processes

lets create a couple of shell scripts like this: 1) ns_shared: #! /bin/rc cat /n/tmp/foo ramfs -m /n/tmp # start another ramfs in the child's namespace echo something > /n/tmp/foo cat /n/tmp/foo exit 2) ns_RFNAMEG #! /bin/rc rfork

[9fans] Namespace inheritance between processes

Hi 9 fans, I'm trying to figure out how namespace inheritance between process groups works. Let's say I have a process A which forks a child process B with the RFNAMEG so it receives a copy of A's namespace. If process A then makes a change to its namespace, will process B see that change? Or
