[Bug 1324698] [NEW] home ecryptfs directory not accessible in X on boot

[Dash]

Public bug reported:

Upgrade a notebook with SSD disk and /home/<user> directory in ecryptfs,
from 12.04 to 14.04. After installation, on each reboot, the ecryptfs
<user> partition is encrypted mounted when checking in console mode
(tty[1,2,...,6] but *not* when entering users credentials in X greeting
window. If, before entering those credentials, we open a tty console and
run "sudo service lightdm restart" and switch back to X greeting
windows, all is good.

In the case of login without restarting lightdm, behaviors are:

- ls -al shows cached directories created from time of login
- ls shows a README.TXT symbolic link to /usr/share/ecryptfs-utils/ecryptfs-mount-private.txt
- ls shows a ecryptfs-mount-private.desktop symbolic link to /usr/share/ecryptfs-utils/ecryptfs-mount-private.desktop  
- all files and directories from real <user> encrypted directory are missing

The disk is one partition

UUID=9b12bd21-53d4-38f5-c474-674e05cd8d7c /               ext4
rw,relatime,discard,errors=remount-ro,data=ordered 0       1
