Research direction

Start with the DSC extension installation of dsc-1.1.1-294 and compare the linked microsoft/omi#641 and PowerShell-DSC-for-Linux#601 reports. Reproduce the omiagent crash and trace its interaction with libbz2.so.1.0.6; done means the extension no longer installs a combination that causes the reported segfault.
