Just because the kernel does something differently doesn't mean it's a kernel bug. There's clearly a relevant bug in plymouth that I reported to plymouth upstream two months ago ( https://bugs.freedesktop.org/show_bug.cgi?id=87993 ) but forgot to mention here. Since there has been no response to that report, maybe it's time to fix the bug in ubuntu's plymouth package.
