SUMMARY

Using the default centos7 conductor image to build a container using the spk83.dumb-init fails, due to the centos container not having sudo installed.

Is there a good reason for this, as the ubuntu container seems to have it - when looking at a similar issue.

[Voronenko]

when building container you generally do not need sudo, so it is normal that it is not present.
