Situation: You are executing other scripts from a manifest. This script fails, but cdist does not recognise the error. An example script would be something like this:
% cat ~/.cdist/manifest/init "$__manifest/special" % cat ~/.cdist/manifest/special #!/bin/sh echo "Here is an unclean exiting script" somecommandthatdoesnotexist echo "I continue here although previous command failed"
We can clearly see that somecommandthatdoesnotexist will fail in ~/.cdist/manifest/special. But as the custom script is not called with the -e flag (exit on failure) of shell, it does not lead to an error. And thus cdist sees the exit 0 code of the last echo line instead of the failing command.
All scripts executed by cdist carry the -e flag. To prevent the above from happening, there are two solutions available:
# Execute as before, but abort on failure sh -e "$__manifest/special" # Source the script in our namespace, runs in a set -e environment: . "$__manifest/special"
