Sorry, my previous reply was quite bogus, too early still. I suppose that output comes from under upstart, so /dev/mapper/vg-swap is the *result* of crypttab.
The blurred screenshot says "invalid argument". So please leave that line disabled, and once the system is running, try sudo SYSTEMD_LOG_LEVEL=debug strace -fvvs1024 -o /tmp/t /lib/systemd /systemd-cryptsetup attach vg-swap dev/dm-6 /dev/urandom swap,cipher =aes-cbc-essiv:sha256 This should give some "invalid argument" at some point, does it? For me this command works fine on current vivid. If it reproduces the "invalid argument" for you, please copy&paste the output and /tmp/t. Thanks! ** Summary changed: - can't boot with systemd + boot fails on cryptsetup random swap partition with "invalid argument" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1443413 Title: boot fails on cryptsetup random swap partition with "invalid argument" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1443413/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
