NAME
       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
