   2 ## 09_fix_resolvconf_pxeboot.dpatch by Michael Prokop <mika@grml.org>
   3 ##
   4 ## All lines beginning with `## DP:' are a description of the patch.
   5 ## DP: fix resolvconf handling when booting via PXE
   6 ##
   7 ## When installing grml for PXE boot the system has network after
   8 ## boot but no usable DNS. /etc/resolv.conf is empty except the
   9 ## warning to not edit this file manually but to use the resolvconf
  10 ## tool.
  11 ##
  12 ## The problem is, that the 23networking scripte in the initrd
  13 ## correctly creates the resolv.conf, but it's being overwritten by
  14 ## the resolvconf utility on boot.
  15 ##
  16 ## The fix for now is to remove the symlink so resolvconf breaks
  17 ## early and DNS is working then.
