I put the arguments found in /proc/mounts (plus the user option) into an entry in /etc/fstab, now the `mount -i ~/.crypto-dir` and `umount -i .crypto-dir` commands will mount & umount the directory without a hitch. But this only works as root, as non-root I get: $ mount -i /home/john/.crypto-dir mount: No such file or directory then after successfully applying the above command as root: $ umount -i /home/john/.crypto-dir umount: only root can unmount /home/john/.crypto-dir from /home/john/.crypto-dir Also, if I do `keyctl clear @u` after a `umount -i .crypto-dir`, when I try `mount -i ~/.crypto-dir` I get "mount: No such file or directory". I can go back & manually do `mount -t ecryptfs .crypto-dir .crypto-dir` and that mounts the directory again. And when I try `ecryptfs-add-passphrase` at any point, there is this: ecryptfs-add-passphrase: symbol lookup error: ecryptfs-add-passphrase: undefined symbol: ecryptfs_get_passphrase Regards, John -- John Magolske http://B79.net/contact _______________________________________________ Mailing list: https://launchpad.net/~ecryptfs-users Post to : [email protected] Unsubscribe : https://launchpad.net/~ecryptfs-users More help : https://help.launchpad.net/ListHelp
