Description Tom Siewert 2021-04-03 13:24:18 UTC 
Created attachment 1768799 [details]
rdsosreport.txt which gets generated by dracut if the boot fails.

Description of problem:
After upgrading from Fedora Netinst 33 to Fedora 34 Beta, I was facing the issue that I did not get any prompt to type in my password to decrypt the disk (full disk encryption) and the fallback to dracut emergency shell starts.
A bit of debugging in the emergency shell showed me that systemd-ask-password-plymouth.path will be stuck in state `active (waiting)` so `systemd-ask-password-plymouth.service` will not start and fail as the condition `PathExists=/run/plymouth/pid` was not met.

After manually creating this directory the service started successfully.


Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Install a Fedora 33 system via Netinst (with Window managers), full disk encryption, LVM2 in UEFI mode
2. Update your system
3. Install dnf-plugin-system-upgrade and upgrade your system to F34 beta

Actual results:
After upgrading, Plymouth will load infinitely until dracut emergency shell fallback starts.

Expected results:
Plymouth asks for a password to decrypt the disk.

A similar issue is reported in https://bugzilla.redhat.com/show_bug.cgi?id=1945530.

This might be related to a recent release of Dracut 0.53 (up from 0.51): https://bugzilla.redhat.com/show_bug.cgi?id=1945596

Can confirm it. A downgrade to Dracut 0.51 "fixed" it.
