* This allows mounting from /etc/fstab. See
(#45)[https://github.com/rfjakob/gocryptfs/issues/45] for details.
* Mounting on login using pam_mount works as well. It is
[described in the wiki](https://github.com/rfjakob/gocryptfs/wiki/Mounting-on-login-using-pam_mount).
* To prevent confusion, the old `-o` option had to be renamed. It is now
called `-ko`. Arguments to `-ko` are passed directly to the kernel.
* New `-passfile` command-line option. Provides an easier way to read

Mounting gocryptfs on login using pam_mount
===========================================
This works on Fedora 24 with active SELinux. Feedback on other platforms
is welcome.
gocryptfs
---------
Copy the `gocryptfs` binary and `gocryptfs_pam_mount.bash` into
`/usr/local/bin` .
The bash wrapper is neccessary because of the different calling
conventions between pam_mount and gocryptfs.
Create a gocryptfs filesystem:
```
$ mkdir /home/testuser/cipher /home/testuser/plain
$ gocryptfs -init /home/testuser/cipher
```
pam_mount config
----------------
Put the following into `/etc/security/pam_mount.conf.xml`, just before
the closing `</pam_mount>` tag at the bottom:
```
<volume user="testuser" fstype="fuse" options="defaults"
path="/usr/local/bin/gocryptfs_pam_mount.bash#/home/%(USER)/cipher"
mountpoint="/home/%(USER)/plain" />
```
Replace `testuser` with your user name.
If you want to disable the display of the masterkey on mount, replace
`options="defaults"` with `options="quiet"`.
PAM config
----------
An example `/etc/pam.d/login` on Fedora 24 is shown below. pam_mount
MUST be called AFTER `pam_selinux.so open` because that puts us in the
right SELinux context. If are logging in via gcm, also add the line in
`/etc/pam.d/gdm-password`.
```
#%PAM-1.0
auth substack system-auth
auth include postlogin
account required pam_nologin.so
account include system-auth
password include system-auth
session required pam_selinux.so close
session required pam_loginuid.so
session optional pam_console.so
session required pam_selinux.so open
session required pam_namespace.so
# vvv insert pam_mount here
session optional pam_mount.so
# ^^^ insert pam_mount here
session optional pam_keyinit.so force revoke
session include system-auth
session include postlogin
-session optional pam_ck_connector.so
```
Encrypting the whole home directory
-----------------------------------
Use this volume definition in `/etc/security/pam_mount.conf.xml`:
```
<volume user="testuser-whole-home" fstype="fuse" options="nonempty,allow_other"
path="/usr/local/bin/gocryptfs_pam_mount.bash#/home/%(USER).cipher"
mountpoint="/home/%(USER)" />
```
Replace `testuser-whole-home` with your user name.
