When running under tmux, the script cannot create a screen session for the d4m tty to run the setup script on the moby vm. As a result, we loop on waiting for d4m-done to appear in /tmp, which will not occur since since the script was not started.
Solution:
Check if tmux is running via environment variables that it sets, and exit with status 1 if they are detected.
Before:
$ ./d4m-nfs.sh
[d4m-nfs] Copy the Moby VM APK Cache back.
[d4m-nfs] Create the script for Moby VM.
[d4m-nfs] Start and restop nfsd, for some reason restart is not as kind.
Stopping the nfsd service (use 'disable' to make permanent)
Starting the nfsd service
[d4m-nfs] Wait until NFS is setup..
[d4m-nfs] Wait until D4M is running.
[d4m-nfs] Setup 'screen' to work properly with the D4M tty, while at it name it 'd4m'.
[d4m-nfs] Run Moby VM d4m-nfs setup script.
No screen session found.
[d4m-nfs] Waiting until d4m-nfs setup is done...............................
After:
$ ./d4m-nfs.sh
[d4m-nfs] This script cannot be run under tmux. Exiting.
