FreeBSD ISO layout
From FreeBSDwiki
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:
6.2-RELEASE-i386-bootonly.iso 24848 KB 01/12/2007 12:00:00 AM 6.2-RELEASE-i386-disc1.iso 587138 KB 01/12/2007 12:00:00 AM 6.2-RELEASE-i386-disc2.iso 654402 KB 01/12/2007 12:00:00 AM 6.2-RELEASE-i386-docs.iso 192414 KB 01/12/2007 12:00:00 AM CHECKSUM.MD5 1 KB 01/12/2007 12:00:00 AM 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:
