usplash receives repeated "CLEAR" commands while in verbose mode

Here is a video, to demonstrate. I booted with "quiet" removed from kernel cmdline, and hit esc at disk-checks.

Instead of changing anything in mountall, how about disabling the usplash CLEAR command when in verbose mode? Perhaps even disabling usplash itself in verbose mode?

The mountall change for this bug unfixes bug #215666.

CLEAR is useful for a few situations. Disabling it in verbose mode
doesn't seem right, and disabling usplash all-together would be a really
nasty regression.

I don't believe that to be a bug -- why would I want the status of my fsck
to vanish the instant it finishes?

Kees,

The main issue with #215666 was strings like “one of the mounts listed in fstab cannot yet be mounted” being left on the screen after the mount was in fact successful.

This bug was fixed in the package mountall - 1.0

---------------
mountall (1.0) karmic; urgency=low

  [ Kees Cook ]
  * Call out to restorecon after mounting tmpfs filesystems. LP: #456942.

  [ Johan Kiviniemi ]
  * Fix a bug introduced by the 0.2.6 change. In certain situations, we’d
    quit even though we’re still waiting for some filesystems to be
    mounted. LP: #456806.

  [ Scott James Remnant ]
  * Don't clear the splash screen when we're waiting for filesystems,
    instead just output following whatever else is there. In non-verbose
    mode this won't look any different, but it means we don't clear previous
    verbose mode text. LP: #458389.
  * Only update the "waiting for one or more mounts" text if there's actually
    a change in the set we're waiting for; this removes the need for a CLEAR
    this case anyway.
  * Don't say we're waiting for mounts we're, in fact, not waiting
    for. LP: #459859.
  * Stop mountall (normally) when entering recovery mode. LP: #458060.

  * Clean up source tarball. LP: #460348.
