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
