Comment 107 for bug 1834875

We are seeing some failures still in Eoan (not Focal) with tracebacks involving growpart:

2020-05-29 10:14:29,218 - util.py[DEBUG]: Running module growpart (<module 'cloudinit.config.cc_growpart' from '/usr/lib/python3/dist-packages/cloudinit/config/cc_growpart.py'>) failed

FileNotFoundError: [Errno 2] No such file or directory: '/dev/disk/by-partuuid/465f461c-537a-4d09-acae-cf4469c962c5'

It is still an intermittent failure.
