System information

After the last step of an interactive mount, mo unt will display all the selections made and perform the

mount. This output consists of the command-line option equivalents of each chosen setting. For

example, mounting /ho me with a key type of passphrase, aes cipher, key bytesize of 16 with both

pl ai ntext passthro ug h and fi lename encrypti o n disabled, the output would be:

Attempting to mount with the following options:

ecryptfs_unlink_sigs

ecryptfs_key_bytes=16

ecryptfs_cipher=aes

ecryptfs_sig=c7fed37c0a341e19

Mounted eCryptfs

The options in this display can then be passed directly to the command line to encrypt and mount a

file system using the same configuration. To do so, use each option as an argument to the -o option

of mo unt. For example:

# mo unt -t ecryptfs /ho me /ho me -o ecryptfs_unl ink_si g s \

ecryptfs_key_bytes= 16 ecryptfs_ci pher= aes ecryptfs_si g = c7fed 37c0 a34 1e19
