ecryptfs mount options
I was having trouble tracking down the ecryptfs mount options that can be used to stop the mount.ecryptfs helper utility from prompting quite so much. I tested this on Ubuntu 10.10. ecryptfs_verbosity claims to be the option that I really want to change, but I couldn’t get this one working.
You can add these options to your /etc/fstab. Their values are partially documented here: http://ecryptfs.sourceforge.net/README
Here’s what I added to my /etc/fstab to stop mount.ecryptfs from prompting for anything besides the password on Ubuntu 10.10:
/root/.crypto /root/crypto ecryptfs noauto,ecryptfs_cipher=aes,ecryptfs_key_bytes=32,ecryptfs_passthrough=n,ecryptfs_enable_filename_crypto=n 0 0
Full option listing (and how I finally found them all…):
% strings mount.ecryptfs | grep ecryptfs_
