If there's an easy way to detect when a directory is inside an ecryptfs volume, I'd be happy to make the assistant automatically enable fsync on it. ;)

What good idea! I've turned on `core.fsyncobjectfiles`. This should definitely help avoid the worst damage when ext4 filesystems get unmounted while dirty. Thank you very much for addressing this issue so quickly, even if though has more to do with ext4 than git annex.
develop: Thank you for the suggestion to use LUKS; that's good to know.

If the string `\" ecryptfs \"` (with surrounding spaces) appears in `/etc/mtab`, then there's at least one ecryptfs volume on the system. More specific parsing will tell you where it's mounted.
Ubuntu released a new kernels fixing the worst ecryptfs bugs in 12.04 LTS. The current version is OK, but perhaps not exactly great. Some older versions are public menaces with awful data corruption bugs.
