Re-provision VM $"vagrant"provision When machine is running

Chef or Puppet?

Problems with provisioning

•Provisioning is often slow (especially when installing lots of packages) •Quality of public cookbooks/manifests •Support on cookbooks/manifests •Writing it yourself can be difficult •Some cookbooks/manifests only work on certain Linux distros Problems with provisioning

Re-distribute current VM $"vagrant"package •Possible solution for slow provisioning •Is not the same as vagrant box repackage •Use exported box as new base box •No provisioning required on startup •Possibility of doing “light” provisioning instead
