umount.ecryptfs_private(1)	   eCryptfs	    umount.ecryptfs_private(1)

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,
       who  ares  members  of  ecryptfs	 group, 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
