[Bug 876626] Re: Unlocking the second crypto disk (/home) echos password on console

[Scott James Remnant]

-c1326 doesn't change the console handling, it merely changed the error
case:

-               if (system_setup_console (CONSOLE_OUTPUT, (! restart)) < 0)
+               if (system_setup_console (CONSOLE_OUTPUT, (! restart)) < 0) {

The Plymouth-safe console behavior was never committed upstream, but was
part of the Ubuntu delta applied to 0.6.5-5, this patch has apparently
been dropped:

http://launchpadlibrarian.net/41179455/upstart_0.6.5-4_0.6.5-5.diff.gz

-	/* Set the standard file descriptors to the ordinary console device,
-	 * resetting it to sane defaults unless we're inheriting from another
-	 * init process which we know left it in a sane state.
-	 */
-	if (system_setup_console (CONSOLE_OUTPUT, (! restart)) < 0)
-		nih_free (nih_error_get ());

This was never merged upstream because I'm not Lennart, and I don't go
around saying things like "all relevant distributions use Plymouth to
set up the system console" :p Something has to set up the console
correctly and other Upstart users (e.g. Chrome OS) don't even have an
initramfs or initrd so need init to do that, as the first thing being
run.

The correct upstream fix obviously would be to conditionally set up the
system console in some manner, dependent on whether or not it's already
"owned" by a running process or whether init is truly the first process
to be run.

Bug description:
  Boot

  1.) Enter crypto phrase for /
  2.) ... init things...
  3.) Enter crypto phrase for /home

  On 3rd the password is echoed as such, only after pressing enter it prints the passwords again with stars.
  Enter passphrase: ABCDEF ENTER
  Enter passphrase: *******

  Workaround:  install the plymouth-theme-ubuntu-logo package if not
  already installed, and boot with the 'splash' option
