Thank you for taking the time to report this bug and help to improve
Ubuntu.
The behavior shown in comment #3 appears to be a bug in plymouth's text
plugin: when two processes (mountall and cryptsetup) are talking to
plymouth at the same time, plymouth fails to correctly display the
passphrase prompt, seemingly (based on what I catch sight of as things
flash by) because the prompt gets overwritten by the mountall message.
If I hit the spacebar the prompt is re-rendered, but some of the
keypresses also appear not to be registered correctly perhaps because
they're being eaten on behalf of mountall.
This bug is not reproducible with the default 'script' plugin used by
the Ubuntu theme (which requires a framebuffer renderer), nor is it
reproducible when mounting the root partition in the initramfs because
cryptsetup is the only thing talking to plymouth at that point.
Setting importance to 'medium' because it's expected that we won't have
to use the text plugin for lucid on most hardware once the framebuffer
renderer is ported to work with the default VGA16 framebuffer.
** Package changed: cryptsetup (Ubuntu) => plymouth (Ubuntu)
** Changed in: plymouth (Ubuntu)
Importance: Undecided => Medium
** Changed in: plymouth (Ubuntu)
Status: New => Confirmed
** Summary changed:
- Passphrase request at bootup doesn't work properly
+ mountall status clobbers passphrase prompt with plymouth text plugin
