The difference is I install PAM before I install shadow. If you look at
the shadow page in BLFS it has:
install -v -m644 /etc/login.defs /etc/login.defs.orig &&
for FUNCTION in LASTLOG_ENAB MAIL_CHECK_ENAB \
PORTTIME_CHECKS_ENAB CONSOLE \
MOTD_FILE NOLOGINS_FILE PASS_MIN_LEN \
SU_WHEEL_ONLY MD5_CRYPT_ENAB \
CONSOLE_GROUPS ENVIRON_FILE \
ULIMIT ENV_TZ ENV_HZ ENV_SUPATH \
ENV_PATH QMAIL_DIR MAIL_DIR MAIL_FILE \
CHFN_AUTH FAILLOG_ENAB QUOTAS_ENAB FTMP_FILE \
OBSCURE_CHECKS_ENAB CRACKLIB_DICTPATH \
PASS_CHANGE_TRIES PASS_ALWAYS_WARN ISSUE_FILE
do
sed -i "s/^$FUNCTION/# &/" /etc/login.defs
done
So shadow doesn't write to /var/log/btmp if it's installed after PAM.
Thanks for your help looking at this. I'd forgotten about modifying
/etc/login.defs when installing shadow after PAM.
