Probably because ping uses setuid. http://stackoverflow.com/a/11148167/539465 > Could maybe the test suite discard all lines from stderr containing > the string "libeatmydata.so" before checking if it's empty o not? Actually, it's the main code which raises the error, and I don't like the idea of adding a special case for this. However, this would fix your problem if it gets merged: https://sourceware.org/bugzilla/show_bug.cgi?id=20172 And Limnoria would not even need to be patched, as environment variables for the subprocess are inherited. An other possibility would be to add an option to tell the test suite to skip tests which use setuid binaries. This feature could also be useful in some other contexts, for instance on environment which forbid setuid executables (like Travis CI, although it whitelisted ping since)
