I'm using ecryptfs for a folder not within my home directory. The authentication is passphrase only. If I mount the folder with the ecryptfs mount-helper all is working fine.
If I then unmount the folder and mount it again not using the mount-helper (
-i option), the folder is mounted again with no issue.
Then I reboot the machine and add a key to the key-ring with
ecryptfs-add-passphrase. After this I try to mount again without the mount-helper but this will not work.
This is my mount command:
mount -i -t ecryptfs -o "ecryptfs_sig....." /mnt/crypt_folder /mnt/crypt_folder
