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

[Hans-Gregor Gehrke]

I used the graphical "Software Updater", which is also used for regular
updates (clicking on major system update). The update was started from
the encrypted system, all required packages were downloaded from default
sources defined in the Ubuntu repertory.  During the update procedure I
chose all default option (none related to encryption but rather to
configurations of e.g Mysql etc.)

(Also the decryption was done using just the installed system by coping
the data of "home" to a different hard drive, removing the home folder
(using a different sudo-account), finally. restore home directory
without encryption. This procedure is probably best done from pure
command-promt to avoid troubles with locked files in the cache caused by
the graphical interface.)

** Description changed:

  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.
