debian squeeze slow dns queries due to glibc bug

Hi there,

I was wondering about that every fresh debian squezze install drops 2 out of 3 dns queries with ipv6 enabled in kernel

After struggling arround for some time, I found the problem…
Looks like an glibc bug:

You need to add a line in your resolv.conf which is not listed in the manpage of resolv.conf (nice)

options single-request

or you edit your /etc/resolvconf/resolv.conf.d/tail
then the resolv.conf is automtically generated with this option

Have fun!
