Actually, I did not. The reason for that decision was that I could live with to have / on BTRFS, at least on the computer I use for test purposes only. All the other partitions use XFS (except swap). With that setup all partitions, including /, are now encrypted.
When I tried to use XFS on / in combination with encryption the error message during installation reads:
dracut-initqueue [(process number)]: Warning: dracut-initqueue: starting timeout scripts
dracut-initqueue [(process number)]: Warning: dracut-initqueue: timeout, still waiting for following initqueue hooks:
dracut-initqueue [(process number)]: Warning: /lib/dracut/hooks/initqueue/finished/devexists-\x2fdev\x2fdisk\x2fby-uuid\x2fde8836f5-06cb-4584-a9e8-7537aeb27953.sh: "[ -e "dev/disk/by-uuid/de8836f5-06cb-4584-a9e8-7537aeb27953" ]"
This message repeats itself several times circa 200 seconds after the installation process has begun and inevitably ends with a warning: āCould not bootā. After that systemd (process 1, of course) says on standard out or standard error, I donāt know, āStarting Dracut Emergency Shellā. Thirty milliseconds later systemd says it received SIGRTMIN+21 from plymouthd.
If this the case, will it help to try to follow the instructions for an expert installation?
