Title: sys-fs/cryfs-0.10.2 update 
Author: Andreas Sturmlechner <asturm@gentoo.org>
Content-Type: text/plain
Posted: 2019-10-26
Revision: 1
News-Item-Format: 1.0
Display-If-Installed: <sys-fs/cryfs-0.10

Filesystems created with CryFS 0.9.x are incompatible with the new storage 
format. [1] Migration is necessary before mounting with CryFS 0.10 and 
possible for old containers going back as far as CryFS 0.9.4. [2]

However, upstream recommend to create new containers with 0.10 to avoid 
potential data loss from a failed migration, and in order to benefit from all 
performance advantages of the new format.

Before updating, copy all data from cryfs containers to a temporary and secure
location. After the update, move it back into a newly created container. Don't 
forget to remove the temporary files afterwards.
