[Grml] daily-grml base.tgz file

Hi,

I know there is two version of base.tgz files from http://daily.grml.org/. I downloaded http://daily.grml.org/base.tgz, not the 64b version, but its hostname contains "amd64.grml.org". Is it just the etc/hostname file alone, or there are more problems to the base.tgz file?

PS. How do I know if my AMD is running in 32b or 64b mode?

Thanks.
