@xnox,
I tried to enable the plymouth and plymouthd in finalrd, after test, it
could reboot without error message in low rate, most of time the system
will hang at splashing cursor, and sometimes kernel crash. I doubt it
might be the race condition between threads when shutdown. The good
point is that I never saw /oldroot message again, it might be the right
way to fix it, do you have more idea, or did I miss something? Thanks!
