+@subsection PAM Mount Service
+@cindex pam-mount
+
+The @code{(gnu services pam-mount)} module provides a service allowing
+users to mount volumes when they log in.  It should be able to mount any
+volume format supported by the system.
+
+@defvar {Scheme Variable} pam-mount-service-type
+Service type for PAM Mount support.
+@end defvar
+
+@deftp {Data Type} pam-mount-configuration
+Data type representing the configuration of PAM Mount.
+
+It takes the following parameters:
+
+@table @asis
+@item @code{rules}
+The configuration rules that will be used to generate
+@file{/etc/security/pam_mount.conf.xml}.
+
+The configuration rules are SXML elements (@pxref{SXML,,, guile, GNU
+Guile Reference Manual}), and the the default ones don't mount anything
+for anyone at login:
+
+@lisp

+
+Some @code{volume} elements must be added to automatically mount volumes
+at login.  Here's an example allowing the user @code{alice} to mount her
+encrypted @code{HOME} directory and allowing the user @code{bob} to mount
+the partition where he stores his data:
