gendisk(1) General Commands Manual gendisk(1) NAME gendisk - produce distribution disk media SYNOPSIS /usr/bin/gendisk [ -wv ] [ -d ] [ hostname:]product-code special DESCRIPTION The gendisk utility is used to produce distribution media on removable moving-head disks (not floppies). The utility searches /etc/kitcap for the product-code (as provided by the user on the command line), creates a new file system on the partition defined in the kit description, mounts the disk, transfers files and subsets as described in the kitcap kit description, uses sum(1) to verify files for accuracy in transfer, and then unmounts the file system. The gendisk utility can create mul- tiple directories on the disk for separate products, and can also com- bine multiple products into one product, all controlled by /etc/kitcap. The optional hostname: argument is the name of a remote TCP/IP network machine that contains the kitcap file. The utility searches /etc/kit- cap on the remote machine for the product-code and uses it for creating the media. The colon (:) is a required delimiter for TCP/IP networks, and space is permitted between the colon and the product-code. For ex- ample, if the product code is ULT-4.2-V-BW, and the kitcap file to be used is on node mynode, the proper syntax for this option is: myn- ode:ULT-4.2-V-BW The product-code is a user defined code. It can be any set of numbers or letters, and is usually formed in a way to have some meaning as to the product that it describes. For example, if the product's name is MYP and its version is 1, a proper product-code for that product might be MYP010. The special argument indicates that the device is a special device such as /dev/rrz1a. The actual partition that the utility will write the files on is defined in the kitcap description for the product-code that is being used. Therefore, it makes no difference what partition is ap- pended to the special device file used on the command line. FLAGS -d Specifies that the gendisk is to create a distribution disk inn direct CD format. Direct CD format means that the distribution disk contains file systems that are laid out just as the soft- ware would be installed on the system. -w Specifies that the gendisk is to write but not verify the prod- uct media. -v Specifies that the gendisk is to verify the product media with- out writing it first. If neither flag appears on the command line, the utility writes and then verifies the files in the kit descriptor. The -d flag must be used by itself or after the -v and -w flags. RESTRICTIONS You must be a superuser to run this program. If the optional hostname is used, you must be able to access files on the remote host as supe- ruser. If the optional hostname is not used, you can access the files used by gendisk only if the local hostname is added to the local /.rhosts file, as follows: hostname root The gendisk command asks whether you want to clean the whole disk be- fore writing to it. If you answer affirmatively, gendisk erases the entire contents of the disk and writes a new disk label using default information.
