The /etc/resolv.conf file is only for DNS lookup, general hostname
lookups use the Name Service Switch (/etc/nsswitch.conf) to decide the
order of lookups. Each of those services (including DNS) may dynamically
load modules (/lib/libnss*) to perform the actual service specific
hostname lookup.

If these modules are loaded after the start of icecast (the default case
on linux) and more specifically after the chroot then these also have to
be in the chroot jail as well
