# RHCOS uses static PAM files not managed by authselect.
# Although /usr/bin/authselect exists on RHCOS 9, using it rewrites
# the PAM stack with RHEL 8 era templates (pam_fprintd.so, etc.)
# that don't match the actual RHCOS 9 PAM configuration, causing
# the compliance scan to still report FAIL after remediation.
# Use direct sed to surgically remove nullok instead.
