[Bug 1311883] [NEW] Nested Encryption (eCryptfs home-folder on encrypted partion) after update to Ubuntu 14.04

[Hans-Gregor Gehrke]

Public bug reported:

Hi,

after upgrading from Ubuntu 13.10 to 14.04 my home-dir was automatically encrypted using eCryptfs. Although useful, my home-dir is within an encrpyted volume. And now encryption is nested. As a result, my data-throughput droped to 30 Mb/s (120 MB/s before on SSD within encrypted volume)
I did solve the problem by removing the encryption layer added by eCryptfs (ecryptfs-setup-private --undo). Now I would like to suggest adding a user querry for adding the encryption during update, at least, if encrypted volumes are already in use for the home-dir.
