umount.ecryptfs_private − eCryptfs private unmount helper.
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 available for the umount.ecryptfs_private command:
|
−f |
Force the unmount, ignoring the value of the mount counter in /tmp/ecryptfs-USERNAME-Private |
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).
˜/.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
