plymouth (Ubuntu)

Bug Description

0.9.3-1ubuntu4 removed the implicit wait on the daemon. this seems to have broken iso reboots in qemu with uefi (no secureboot) and qxl vga.

- start ubuntu-desktop iso
- install
- restart system
- plymouth never comes up instead you get lovely IO errors

if you boot console=ttyS0 (and have a console attached obviously) you'll further more see that the "remove medium and press enter" message is actually printed there. my assumption is that casper-stop in some capacity actually relied on plymouth --ping delaying the stop until plymouthd actually responds. since that is no longer the case things implode.

in general it seems to me that the change in ubuntu4 is super invasive in outright changing implicit upstream behaviour which any number of things might rely on.
