For people trying to help, here's an example:
augtool> ls /files/etc/pam.d/sshd/
#comment[1] = PAM configuration for the Secure Shell service
#comment[2] = Read environment variables from /etc/environment and
#comment[3] = /etc/security/pam_env.conf.
1/ = (none)
#comment[4] = In Debian 4.0 (etch), locale-related environment variables were
moved to
#comment[5] = /etc/default/locale, so read that as well.
2/ = (none)
#comment[6] = Standard Un*x authentication.
include[1] = common-auth
#comment[7] = Disallow non-root logins when /etc/nologin exists.
3/ = (none)
augtool> ls /files/etc/pam.d/sshd/3
type = session
control = required
module = pam_limits.so
