I am trying to reproduce this setting, but it does not seem to work anymore. I keep getting the error: execve failed: No such file or directory.
One of the reasons is that /usr/local/bin/Rserve is no longer a standalone executable, and is now initiated using R CMD Rserve. However, after making the appropriate changes to the .ini, I still get the same error.
Anyone successfully reproduced this setting with a recent R/Rserve/Jailkit?
