Comments are welcome! Yup, AFAIK metacluster and zap do this too. I don't think there is any question about whether we want to support this, but rather what the user-kernel API should look like. Perhaps the easiest "API" is to have the userspace program rewrite the checkpoint image, but that probably isn't quite as simple as just substituting #s in the image, bc we'll have to also find the place where the source of the original fd was specified and tweak that. I assume this is one of the things Oren would have 'cradvise()' do, and at this point that sounds nice to me - might be worth seeing how the community reacts. Sentiments on such things change, after all. Have there been any other suggestions? -serge _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
