Version 2.408.65 of livecd-rootfs has fixed this issue. Test case: Built a box with the version of livecd-rootfs
vagrant box add build.output/livecd.ubuntu-cpc.vagrant.box --name xenial-test vagrant init xenial-test vagrant up vagrant ssh default Run `df -H` inside the vagrant box Observe Disk size of drive mounted at / and observe that the disk is ~ 40G To confirm that this won't break users upgrading to this box, but with < 40G disks, I checked the size of the VMDK backing the box. It was listed at 1.1G. I created a 15G file with `dd if=/dev/urandom of=filename bs=1024 count=15M` I was able to observe the VMDK growing by 15G. So if a user were to have a 10G box fully allocated, and then upgrade to the new box built with the latest version of livecd-rootfs, the user would not be impacted until they tried to fill up the 40G. ** Tags removed: verification-needed-xenial ** Tags added: verification-done-xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580596 Title: Xenial & bionic vagrant box disk size is too small To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1580596/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
