Hi Sakaki, great guide you've made here! Very clear and well motivated instructions.

However, I experience a problem at the end of this chapter. When I reboot, the system finds the USB-drive and prompts for the passphrase. When I enter the passphrase the root partition fails to mount. I get the following message on startup:

...output supressed...

>> Removable device /dev/disk/by-partuuid/[correct PARTUUID for my USB-drive] mounted
>> luks-key.gpg on device /dev/disk/by-partuuid/[correct PARTUUID for my USB-drive] found
Enter passphrase:

...loads some additional USB-devices and then waits for passphrase...
...I enter passphrase here...

I have rebuilt the kernel two times with different manual configurations without any success. I have also tried the other tips at the end og the chapter without any success.

I have followed the guide to the letter with two exceptions:

  • I only have one partition on my SSD as i don't intend to dualboot.
  • I don't have a /home partition, only swap and root

Any ideas what the problem may be?

Hi, did you definitely set a systemd profile and update @world during this previous step of the guide? That should have created the required init (/usr/lib/systemd/systemd) on your mapped vg1-root. Try dropping to a shell where prompted (at the end of the failed boot, above) and having a look at what is actually present in your root directory.

That did the trick! I had chosen the wrong profile. When I changed this and updated @world it worked like a charm.

Thanks for the quick reply!
