Make sure your md5sum binary is also on immutable media. It doesn't do you any good to have known good checksums, if the binary that does the checking can be hacked to tell you what the hacker wants it to tell you. -- Andrew Edelstein http://andrew.pure-chaos.com Colonel Slade: There are 2 kinds of people in this world, Charlie.
