Comment 7 for bug 359997

When that dialogue popped up for me after booting my freshly installed Jaunty with encrypted LVM, I ran into a problem similar to François's (Hi, btw):

-------------------------------
~$ ecryptfs-unwrap-passphrase
Usage:
ecryptfs-unwrap-passphrase [file]
or
printf "%s" "wrapping passphrase" | ecryptfs-unwrap-passphrase [file] -
-------------------------------

Looks like it didn't find it's way to ~/.ecryptfs/wrapped-passphrase by default, where the file actually was.
