## DP: fix resolvconf handling when booting via PXE
##
## When installing grml for PXE boot the system has network after
## boot but no usable DNS. /etc/resolv.conf is empty except the
## warning to not edit this file manually but to use the resolvconf
## tool.
##
## The problem is, that the 23networking scripte in the initrd
## correctly creates the resolv.conf, but it's being overwritten by
## the resolvconf utility on boot.
##
## The fix for now is to remove the symlink so resolvconf breaks
## early and DNS is working then.
