IMHO it will come in handy to include this information in README.Debian
- or as comment in the example config file.

just my 2 cent,

The distribution package makers should take more care in such cases. If
you want to use DNS names then the mechanism for name lookups needs to
be complete if you want to use a chroot jail.  This means that the
configuration files or libraries need to exist within the jail.  The
simplest change would be to use the IP address as that won't require the
lookup or avoid the chroot to avoid the restricted directories (use full
paths) but if you want the DNS lookup in a jail then the mechanism is

   read hosts: entry
   lib load of /lib/libnss_... (file, dns etc depending on the protocol)

/lib/libnss_dns... reads /etc/resolv.conf
