Hi Harald, Allow me to answer your question with another question: what are you trying to accomplish here ? Because the separation you are trying to implement doesn't look natural and clearly defined to me. For instance, what if your doit script is called from a subshell of a top-level shell ? Sometimes shells fork without telling you. What behaviour do you want to have in that case ? The only natural distinction you can make is between a boot-environment shell and a login-environment shell. It is pretty easy to distinguish those, via environment variables, and it often makes sense to do so (for instance, you do not want to run services in a login environment - it's a major cause of bugs and sysadmin headaches with System V setups.) Isn't that natural distinction enough for your purposes ? -- Laurent _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
