NAME

dir2img - Create a disk image from a directory for nodemedia upload

SYNOPSIS

dir2img [-e <extra_mb>] [-s <total_mb>] <directory> <imagefile> [<label>]

DESCRIPTION

dir2img packages the contents of <directory> into a FAT-formatted "big floppy" disk image written to <imagefile>. The resulting image is suitable for upload with nodemedia(8) so that its files are presented to a node as removable media. An optional volume <label> may be supplied.

By default the image is sized to fit the directory contents. The -e and -s options allow reserving additional free space.

This command relies on mtools (specifically mformat and mcopy) being installed.

OPTIONS

-e EXTRA_MB
Reserve EXTRA_MB megabytes of free space in the image in addition to the space required for the directory contents.
-s TOTAL_MB
Make the image TOTAL_MB megabytes in total, rather than sizing it to the directory contents.

EXAMPLES

Create an image from a directory
# dir2img /var/tmp/drivers drivers.img
Create a 64 MB labelled image
# dir2img -s 64 /var/tmp/drivers drivers.img DRIVERS
