Hmm, so, there's something else at play here, given:

    quagga: use /bin/false as the login shell

    Use /bin/false as the login shell, just like what Ubuntu does,
    otherwise there might be secure issue.

Is it that proftpd actually needs to spawn a shell somewhere or that
/bin/false simply isn't listed as a valid shell?  (If the latter,
something should've shown up with the quagga commit, shouldn't it?)

Can you guys sync and get back to me on this?

Thanks,
