umount.ecryptfs_private

eCryptfs private unmount helper.

SYNOPSIS

umount.ecryptfs_private [ -f]
NOTE: This program will not clear the relevant keys from the user's keyring. For this reason, it is recommended that users use ecryptfs-umount-private (1)instead!

OPTIONS

Options available for the umount.ecryptfs_private command:

-f Force the unmount, ignoring the value of the mount counter in /tmp/ecryptfs-USERNAME-Private

DESCRIPTION

umount.ecryptfs_private is a mount helper utility for non-root users to unmount a cryptographically mounted private directory, ~/Private.
If, and only if: - the private mount passphrase is in their kernel keyring, and - the current user owns both ~/.Private and ~/Private, and - ~/.Private is currently mounted on ~/Private - the mount counter is 0 (counter is ignored if -f option is used)
This program will: - unmount ~/Private
The only setuid operationis in this program are the call to umount and updating /etc/mtab .
The system administrator can add the pam_ecryptfs.so module to the PAM stack and automatically perform the unmount on logout. See pam_ecryptfs (8).

FILES

~/.Private - underlying directory containing encrypted data
~/Private - mountpoint containing decrypted data (when mounted)
~/.ecryptfs/Private.sig - file containing signature of mountpoint passphrase
/tmp/ecryptfs-USERNAME-Private - file containing the mount counter, incremented on each mount, decremented on each unmount
