Bug Description

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

Proble is worth then that: ones logged, my session gets out of the home ecrypted directory, have to run "ecryptfs-mount-private" from within a terminal or to close my session, restart lightdm, wait few seonds (around 20) and login again. Could be related to screensaver or hibernate features

After investigation, seems more a systemd problem: when I try to mount a sshfs file system in my X session, thinks are going bad. Still OK in console tty1 to 6 :-(

Addendum: console is also broken.

This bug is annoying, nobody uses ecryptfs?

I think the problem comes when an sshfs file system is mounted inside the home directory. For instance I have /home/dash as ecryptfs home directory, and inside I mount 'sshfs remoteServer:myDirectory myDirectory'

Then, when I navigate into the local myDirectory, the ecrypts filesystem shutdown; I have to give back credentials for the 'ecryptfs-mount-private' command, make 'cd' to be back in my home, umount the sshfs filesystem and then restart it. Can be 10 time in 5 minutes as well as 5 times a day ... If it arise too many times, ecryptfs refuses to mount the home directory and I have to restart the computer :-(

The problem is coming with ANY file system mounted inside the ecrypts directory. I faced the problem with an SMB file system.

I removed ecryptfs, since then all is good.
