The attack was used with normal user keys, where the attacker ran an exploit and got root.
This has happened on Cray Linux and on CentOS and RedHat and SLE systems throughout Europe.
Plus, things like parallel debuggers need at least a private/public key pair IN the system to be able to ssh from the login nodes into the compute nodes, even though the batch stuff is managed with munge.
Saying that there's no land for produce alcohol is bullshit. 95% of the cars produced in the last 5 years in brazil are flexfuel, and alcohol-only cars exists there for 30 years.
With gasoline prices going sky high, everyone there uses alcohol to fuel up their cars. And guess what? There's excess in production, which is being exported to US, given their recent interest on new energy sources.
