Questions abou PAM, cracklib and busybox adduser

Hello all

I was just wondering if it makes sense to compile the new linux-pam package that is now in buildroot
with cracklib support ?

I mean, doesn't the busybox adduser applet (or more like, passwd applet) contain somekind of password strength checking (CONFIG_FEATURE_PASSWD_WEAK_CHECK) option already ?

I wan't the best password strength checking possible so should I use plain busybox with CONFIG_FEATURE_PASSWD_WEAK_CHECK enabled or disable that and compile linux-pam with cracklib ?

Best regards:
Stefan

P.S:

Does anybody happen to have a nice patch to busybox deluser applet so that it would support
the -r, --remove option (remove user home directory after user has been removed from /etc/passwd and /etc/shadow)
like shadow package userdel command does ?

Im feeling soooo lazy today to start messing with shadow-4.1.5.1/src/userdel.c and grokking how to add that to deluser :-)
