# Remove pwquality from PAM, to avoid breaking PAM and further dependencies
# This allows pwquality to be neatly severed from the system.

do_install:append:gbmc() {
# Remove reference to pwquality library from PAM config file
sed -i '/pam_pwquality.so/d' ${D}${sysconfdir}/pam.d/common-password
# Remove the first occurrence of "use_authtok" in the first line starting
# with "password". This makes sure that if pam_pwquality.so was the first
# entry, we didn't invalidate the next entry in the stack. If the first
# entry has the "use_authtok" set, this "forces the module to not prompt
# the user for a new password but use the one provided by the previously
# stacked password module". Since there is no "previous" entry, it never
# asks for a password which causes the process to fail.
