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... >> LUKS device /dev/disk/by-partuuid/[correct PARTUUID for my SSD] opened >> Activating Logical Volume Groups 2 logical volume(s) in volume group "vg1" now active >> Activating Logical Volume Groups 2 logical volume(s) in volume group "vg1" now active >> Detected real_resume=/dev/mapper/vg1-swap PM: Starting manual resume from disk >> Initializing root device... >> Mounting /dev/mapper/vg1-root as root... >> Detected fstype: ext4 >> Using mount fstype: ext4 >> Using mount opts: -o ro EXT4-fs (dm-2): mounted filesystem with ordered data mode.

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!
