"Zeroshell weighs in at just over 100 megabytes, making it perfect for embedded devices like PC Engines WRAP boards, Soekris boards, Mini-ITX, and other small form-factor computers. It also installs to a hard drive on ordinary PC hardware, or it can be run from a bootable CD for easy testing. Even production systems can run from the CD; you just need another device for data and log storage."
"Suppose you have a nice little PC Engines WRAP board. Get yourself a 512MB Compact Flash card, and you'll have 400MB available for data storage. Which should be way more than you need, especially if you have a separate syslog server. It is a good practice to store logfiles on a separate device for better security and performance, and fewer writes on your CF card."
