Bug#819288: /tmp is used before /tmp being mounted

[François Scala <francois@scala.name>]

Hello,

While working on a Debian installation base on a ZFS root filesystem 
with LUKS encryption I've encountered a problem with keyboard-setup init 
script that create file in /tmp before /tmp being mounted.

I've write a small script to dump some information just before the "zfs 
mount -a" command.

Here is the process tree

    |-keyboard-setup,1334 /etc/init.d/keyboard-setup start
    |   `-setupcon,1336 /bin/setupcon -k
    |       `-ckbcomp,1387 /usr/bin/ckbcomp -backspace del -model pc105 us

And opened file in /tmp :

    COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF  NODE NAME
    setupcon 1336 root    1w   REG   0,16        0 49551 /tmp/tmpkbd.6Vr3KX
    ckbcomp  1387 root    1w   REG   0,16        0 49551 /tmp/tmpkbd.6Vr3KX

Regards.

François.
