#4571 [dev]/etc/network/interfaces overwriten after first boot

[BaiYuan]

In ubuntu os compute node, I modified /etc/network/interfaces during post-installation; after preseed finished, and system rebooted, /etc/network/interfaces is overwritten;

After I nodeset cn osimage, I modified autoinst file under /install/autoinst:

d-i preseed/late_command string wget http://cat /tmp/xcatserver/install/autoinst/p1vm02.post; \
chmod u+x p1vm02.post; \
cp ./p1vm02.post /target/root/post.script; \
mount -o bind /proc /target/proc -t proc; \
mount -o bind /dev /target/dev; \
mount -o bind /dev/pts /target/dev/pts -t devpts; \
mount -o bind /sys /target/sys; \
chroot /target /root/post.script; \
cp /target/etc/network/interfaces /etc/network/interfaces -----------add this line

After cn installed and rebooted, /etc/network/interfaces is not overwritten;
