Problem with centos2ol.sh migration script
Two weeks ago I got badly bitten by the centos2ol.sh migration script. After running it successfully on about half a dozen of my servers, I decided to migrate my main production server. Unfortunately all I got after the initial reboot was this:
ssh: connect to host sandbox port 22: No route to host
Since the machine is in a datacenter 800 km from where I live, all I could do was setup a new server from scratch and then restore all my backups manually. This was a bare-metal installation, so I spent four long days getting everything back to normal.
I just tested the migration script on a local CentOS installation, and got the same problem. Ran the script, rebooted, and... no net. Since now I have physical access, I can confirm only the loopback interface appears.
So whatever it is the developers were doing these last two or three weeks. Something bad was introduced in the migration script.

PPS: how do you display a code listing in this forum? Are there special tags to use?
