The impression that I get is that encrypting only part of the filesystem is one of the primary use cases of ecryptfs. (For example, if you have a single file system for / but want to have an encrypted home directory.) You may want to consider whether it is preferable to have separate lower and upper mount points, e.g. /opt/backup and /opt/.backup_encrypted or some such. That way, if /opt is mounted and /opt/backup isn't, you don't accidentally clobber or try to use the encrypted backing files. -- Best regards, Michael Chang -- To unsubscribe from this list: send the line "unsubscribe ecryptfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
