Base image can be created, while FRRouting install failed #2

Which results in a corrupted base image, which gets accepted. On building an environment this can lead to the following weird errors:

Workaround, delete the base image and rebuild it:

vnet-manager destroy <config>
vnet-manager destroy <config> -b
vnet-manager create <config>

Fix for this would be to verify the integrity of the base image at the end of creation. Maybe even make a retry wrapper.

This might be fixed by https://github.com/Erik-Lamers1/vnet-manager/pull/14. I haven't been able to reproduce it anymore. Closing for now.
