Is there a question there?
The future appears to be RHEL or Debian. I think I'm going Debian.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are deadest, do not use them.
Use the FAQ Luke

A netmask of 255.255.255.255 is most likely wrong. It only allows you to talk to your own ip address.

Questions about OVH systems need to be addressed to OVH as they do a number of non-standard weird things.
