I can confirm that the crypt parameter without pass= set isn't working in Ubuntu 16.04. At least in the cloud images that I've tested.
I tried it on a freshly launched Ubuntu 14.04 instance and had no problems setting overlayroot=crypt:dev=/dev/vdb and getting everything as expected including logging in /dev/.initramfs/${MYTAG}.log. Then I did the same thing on a fresh Ubuntu 16.04 instance and couldn't use the same overlayroot=crypt:dev=/dev/vdb to get the expected result. Then I just tried overlayroot=/dev/vdb, without encryption, after creating a filesystem on the extra volume and that worked, but I still don't get any logging. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634310 Title: crypt:dev=/dev/vdb parameter does not work with randomly generated passphrase To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-initramfs-tools/+bug/1634310/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
