Hi, The following session was on Fedora 8 (kernel-2.6.23.1-42.fc8, ecryptfs-utils-18-1.fc8):

This could mean that you have typed your passphrase wrong. Would you like to proceed with the mount (yes/no)? yes Would you like to append sig [27aa52467bde3b5d] to [/root/.ecryptfs/sig-cache.txt] in order to avoid this warning in the future (yes/no)? no Not adding sig to user sig cache file; continuing with mount.
