 Instructions how to create a standalone machine that boots directly to reHDD. This is aimed for production use, like several drives a day shredding.
 
 ### Software requirements
 
-* apt-get install hwinfo
-* wget http://ftp.de.debian.org/debian/pool/main/s/smartmontools/smartmontools_7.1-1_amd64.deb
-* dpkg --install smartmontools_7.1-1_amd64.deb 
+* apt-get install hwinfo smartmontools curl
