R help - Dec 2001 - behaviour of Sys.getenv changed after upgrade from 1.3.0 to R1.3.1 debian

Hi, 
both environment variables exist:
> system("echo $hostname")
ernie
> system("echo $HOSTNAME")
ernie

but Sys.getenv reports only one of them:
> Sys.getenv("HOSTNAME")
HOSTNAME
      ""
> Sys.getenv("hostname")
hostname
 "ernie"

What has changed?

Sorry - -
there seems to have been a change from debian 2.2 to 3.0 (unstable): 
HOSTNAME used to be an environment variable, but has changed to be a shell 
variable now....
Thanks for the hint.
