Cloning a FreeBSD system
Simplifying by assuming a single partition, a secure network, and ucspi-tcp already installed on ORIG…
Install fresh hard disk in CLONE, and boot from a FreeBSD rescue floppy.
Rather than installing, go to the “configure” submenu and do “fdisk” and “slice.” Use W Q instead of just Q to quit each one. Install a boot manager just as if you were building a new system.
Go back to the main menu and choose “fixit,” then “live filesystem on CD-ROM.”
Press alt-f4 to switch to the emergency shell.
Start tcpserver on ORIG:
tcpserver -vRHl 0 -c 1 10.23.1.1 1234 sh -c ' echo HTTP/1.1 200 OK echo Content-type: application/octet-stream echo exec dump -0f - /'
Go back to CLONE:
cd /mnt fetch -q -o - http://10.23.1.1:1234/foo | restore -rvf -
