FreeBSD ISO layout

Sample ISO layout of 6.2-RELEASE i386

The directory ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/6.2 lists the following contents:

CHECKSUM.SHA256	                     1 KB 	01/12/2007 	12:00:00 AM

The file CHECKSUM.MD5 contains the following text:

 
MD5 (6.2-RELEASE-i386-bootonly.iso) = 4e8701ac951bc4537f8420fdac7efbb5
MD5 (6.2-RELEASE-i386-disc1.iso) = 3d27214700687c0b5390e8b6dd3706e3
MD5 (6.2-RELEASE-i386-disc2.iso) = fd30bfc65ef8adaa67aeffd07c72bf21
MD5 (6.2-RELEASE-i386-docs.iso) = e3512834982a9beebc3670499c7f3817

The four ISO images were downloaded to an OpenBSD host (from various mirrors) and the signatures were verified using the OpenBSD md5 command. For some other systems the command is md5sum instead.

The four ISO images were then loopback mounted using svnd devices as follows:

 
mkdir boot disc1 disc2 docs 

sudo vnconfig svnd0 6.2-RELEASE-i386-bootonly.iso 
sudo mount -t cd9660 /dev/svnd0c boot

sudo vnconfig svnd1 6.2-RELEASE-i386-disc1.iso 
sudo mount -t cd9660 /dev/svnd1c disc1

sudo vnconfig svnd2 6.2-RELEASE-i386-disc2.iso 
sudo mount -t cd9660 /dev/svnd2c disc2

sudo vnconfig svnd3 6.2-RELEASE-i386-docs.iso 
sudo mount -t cd9660 /dev/svnd3c docs

After mounting the four images as above, the top-level structure of the ISO images was listed out with the command:

find . -maxdepth 4 -type d  

which produces the following output:
