We had that discussion in the past, see
https://groups.google.com/d/msgid/isar-users/1d96541b-1263-773c-d340-35b0c73cb257%40siemens.com,
and that spot was address with a finite loop. Same should be done here.

But note that this is far from complete, see that thread above. Worst
issues: debootstrap has no option to enable a retry.
