< p > Since version 4.8.0 cdist, by default, saves output streams to local cache.
Saving output streams is implemented because important information was lost
during a config run, hidden in all other output.
Now all created output is bound to the context where it was produced.< / p >
< p > Saving output streams include stdout and stderr of init manifest, remote
commands and for each object stdout and stderr of manifest, gencode-* and code-*.
Output stream files are created only if some output is produced. For more info
on these cache files see < a class = "reference external" href = "cdist-cache.html" > Local cache overview< / a > .< / p >
< p > Also, in case of an error, cdist can now exit and show all information it has
about the error.< / p >
< p > For example:< / p >
