This article will explain how you can move your FreeBSD installation from one hard disk drive to another. I have done this many times using the dump/restore utility. Before you begin, be sure you have read this document carefully. Let's assume that our FreeBSD installation is on a 4 gigabyte drive (ide master ad0) and we would like to move it to a new 20 gig drive. What you need to do is remove the old hard disk, install the new [20G] drive as an ide master and perform a minimal clean install of FreeBSD, setting up the partitions exactly how you want them. Be se sure to set the drive as bootable and boot from it one time as a test. Next, put your old [4G] drive back in the system as an ide master and the new [20G] drive in as an ide slave. Boot the system on your old installation in single user mode.
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
