plymouth ask-for-passphrase

[Jay R. Wren]

/usr/share/apache2/ask-for-passphrase has some rediculous plymouth integration with no documentation on how to disable it.

Hi Jay, can you please explain what you expect to happen, and what actually happens?

The code is quite clear, if plymouth is running and available, we ask a question via plymouth's normal methods using the exact same prompt text that apache's internal passphrase module uses. If plymouth is not running anymore, we use the normal method that Apache uses which is to ask the question via the user's controlling terminal. If there is no way to ask the question, we exit with an error.

Clint,

I expect a prompt to be displayed to stdout and prompt for input on stdin. What actually happens is that I start apache via ssh and the prompt is displayed via plymouth on the server's console which I rarely see.

It would be nice if the check was not just "if plymouth is running and available" but instead "if plymouth is running and available and the request was from a tty on which plymouth can prompt a request". Or maybe even just "and we are not on a pseudo terminal"

Here is my patch for ask-for-password in /usr/share/apache2
@@ -23,7 +23,7 @@

 prompt="Apache needs to decrypt your SSL Keys for $sitename ($keytype)
 Please enter passphrase:"
-if [ -x /bin/plymouth ] && plymouth --ping ; then
+if [ -x /bin/plymouth ] && plymouth --ping && ! `tty |grep pty`; then
     echo $prompt | logger
     exec plymouth ask-for-password --prompt="$prompt"
 else

Thanks Jay, thats quite helpful.

I think the answer then is to simply flip the check order around. We'll only try plymouth if apache doesn't have a controlling terminal.

This bug was fixed in the package apache2 - 2.2.21-3ubuntu2

---------------
apache2 (2.2.21-3ubuntu2) precise; urgency=low

  * d/ask-for-passphrase: Flip the logic of this script so that it checks
    first to see if apache is being started from a TTY, and then if not,
    tries plymouth. (LP: #887410)
