yes, here it is:
--- /etc/resolv.conf    2014-07-09 17:35:30.420040438 +0300
+++ yyy/etc/resolv.conf 1970-01-01 02:00:00.000000000 +0200
@@ -1,3 +0,0 @@
-; generated by /sbin/dhclient-script
-search cluserdns cluserdnsus
-nameserver 10.100.1.40

thing is, I'm not sure who generates the content of that file, is it
part of busybox? other utility?

Thanks,

Eial.
