I'm hoping for something along the > lines of 2-4MB and <10s ... I've scaled FreeBSD booting to a multi-user prompt down to about a 8MB system. FreeBSD booting a custom application should be doable in the 2MB range. FreeBSD on a soekris can boot in < 10s to login prompt using the standard rc files, with the 'unused' ones removed. It took about 3s to get to the start of rc on the soekris box. Warnerhome | help
