/etc/environment not read by su?

["Reckhard, Tobias" <tobias.reckhard@secunet.com>]

Hello again,

I've placed the proxy environment variable declarations into
/etc/environment. They appear fine when I ssh into the machine. However,
when I 'su -' to root, they're not set. I enabled root login via SSH
temporarily and when I login as root directly via SSH, the variables are
set.

So my question is: How can I make su read /etc/environment?

Cheers,
Tobias
