iceoryx without the RouDi daemon?
- RouDi daemon does a) setting up the shared memory segments b) creating resources for thing like publishers/subscribers c) monitoring and cleaning up memory if applications are not gracefully terminated d) providing a discovery service
- Ideas:
  - The first user process forks a process for RouDi. RouDi terminates if there is no more user process. Shutdown/Startup races will be a challenge.
  - This could also be an optional thing. I.e. we could support the old way and this approach in parallel.
  - How would we deal with command line parameters? Easiest would be to only use default path to the configuration file.
  - Simon to check how this problem is handled in other systems (e.g. ROS 2 starts a daemon when the command line tools are used).
  - Are the RouDi libraries then linked with the user applications? Alternative: start the applications with ./iox_run my_application, which checks and starts RouDi
  - Having an environment variable, if this is set, it contains the path to the RouDi executable which is then started by the first user process
  - Other possibility would be to have RouDi as a Linux kernel module. Would maybe be a Linux only solution
  - Bob to create an issue with these ideas
iceoryx packages for most common Linux distributions
- Can we use Open Suse's build service which can create packages for many distributions https://openbuildservice.org?
- Christian to create an issue and try this
