Mounting an ISO image on Solaris
Many software packages can be downloaded in the form of an ISO image. ISO images can also be created from CD and saved as ISO images:

$ cat /dev/somecd > somename.iso

Rather than burning the image to a CD-ROM to access its contents, it is easy to mount the image directly into the filesystem using the lofiadm and mount commands.

Given an ISO image in /export/temp/software.iso, a loopback file device (/dev/lofi/1) is created with the following command:

# lofiadm -a /export/temp/software.iso /dev/lofi/1

The lofi device creates a block device version of a file. This block device can be mounted to /mnt with the following command:

# mount -F hsfs -o ro /dev/lofi/1 /mnt

These commands can be combined into a single command:

# mount -F hsfs -o ro `lofiadm -a /export/temp/software.iso` /mnt

Other ISO images can be mounted by incrementing the lofi device:

# lofiadm -a /export/temp/software2.iso /dev/lofi/2
# lofiadm -a /export/temp/software3.iso /dev/lofi/3
etc.

pkg2du

pkg2du(1M)						  System Administration Commands						pkg2du(1M)

NAME

       pkg2du - convert driver packages to Driver Update format

SYNOPSIS

       /usr/bin/pkg2du [-f] [-v] [-d dir] [-o iso] [-l label]
	    [-r release] pkg [pkg ...]

DESCRIPTION

       The  /usr/bin/pkg2du utility takes one or more packages as input and converts them to Driver Update (DU) format. If the -d option is speci-
       fied, the resulting DU directory tree is placed in the directory dir. If the -o option is specified, a Solaris ISO image of the	DU  direc-
       tory  tree is written in the file iso. The ISO image can be burned onto CD/DVD using cdrw(1) or cdrecord(1) (not a SunOS man page) and used
       during Solaris installation.

       At least one of the -d and -o options must be specified. If both are specified, then both an ISO image and a directory tree are generated.

OPTIONS

       The following options are supported:

       -d dir

	   Directory where the DU directory should be created.

       -o iso

	   Create a Solaris ISO image of the DU directory.

       -f

	   If dir/DU or iso exists, remove it without asking first.

       -l label

	   Label/volume name of the ISO image (if -o option is specified).

       -r release

	   Solaris release number to use. It takes the form of the return from uname -r command, for example, 5.10. If	unspecified,  the  release
	   number of the currently running Solaris is used.

       -v

	   Verbose. Multiple -v options increase verbosity.

OPERANDS

       The following operands are supported:

       pkg [pkg...]

	   One or more packages to be converted to DU format.

EXAMPLES

       Example 1 Creating a DU CD/DVD

       The following commands create a DU CD or DVD containing packages SUNWfoo and SUNWbar.

	 # /usr/bin/pkg2du -r 5.10 -o my.iso SUNWfoo SUNWbar
	 # /usr/bin/cdrw -i my.iso
