I was in our server room trying to figure out why our DNS machine was crapping out. Turns out that it just needed a reboot. We have several machines on our network, for instance, one is a firewall box running Smoothwall, another is an FTP/DNS machine, another is mail, and another is a webserver.

After my DNS box adventure, I thought to myself "Why can't I just master a Knoppix to do this if there's an emergency?". Put the basic stuff on there so that it functions enough to keep everyone working until we can get a hard disk replaced.

I know this may be painfully obvious but had anyone else done this or heard of it or know of any related resources? I would really like to go on vacation at some point and not worry about our network.

I asked this same question on the usenet group and the response is below..
----------
"I know PCLinuxOS allows you to use mkfsios (or something like that, please
excuse my ignorance on this command), to effectively take your currently
running system and create a liveCD/dvd that will run that same environment.

Possibly other distros (I would think this is true) allow you to do the
same.

Pretty nifty trick..... "

Is this true? I would really love to spend more time developing code
