Comment 6 for bug 1096307

Ok, if the messages are not showing up, that would seem to be a bug in plymouth rather than in mountall. And it seems to be specific to use of a serial console. Could you post the full contents of /proc/cmdline on the affected system? (Even better would be to run 'apport-collect 1096307' and let apport auto-collect the system data relevant to the plymouth package.)

The plymouth package is a required component and a dependency of mountall; and the 'details' plugin used as the fallback for displaying messages is part of the core plymouth package. So this is unlikely to be a configuration problem.
