NAME

       nbdkit-iso-plugin - create virtual ISO (CD-ROM) from directory

SYNOPSIS

        nbdkit iso [dir=]DIRECTORY [[dir=]DIRECTORY ...]
                   [prog=mkisofs] [params='-JrT']

DESCRIPTION

       "nbdkit-iso-plugin" is a plugin for nbdkit(1) which creates a virtual ISO (CD-ROM) image
       from a directory on the fly.  The files from DIRECTORY are added to a virtual ISO image
       which is served read-only over the NBD protocol.

       This plugin uses xorriso(1), genisoimage(1) or mkisofs(1) to create the ISO content.

       To create a FAT-formatted virtual floppy disk instead of a CD, see
       nbdkit-floppy-plugin(1).  To create a Linux compatible virtual disk, see
       nbdkit-linuxdisk-plugin(1).

EXAMPLE

       Create a virtual ISO which supports Joliet, Rock Ridge and TRANS.TBL extensions, from
       files in a directory:

        nbdkit iso /path/to/directory params='-JrT'

       "params" adds -JrT to the xorriso(1), genisoimage(1) or mkisofs(1) command line,
       specifying the required extensions.  Note that unless you use at least one of these
       extensions, filenames inside the ISO will be truncated because of limitations of the basic
       ISO 9660 format.

PARAMETERS

       [dir=]DIRECTORY
           Specify the directory containing files and subdirectories which will be added to the
           virtual ISO.  Files inside this directory will appear in the root directory of the
           ISO.

           This parameter is required and may be specified one or more times.  If multiple
           directories are specified, they are merged together.

           "dir=" is a magic config key and may be omitted in most cases.  See "Magic parameters"
           in nbdkit(1).

       params='parameters ...'
           Any other parameters may be passed through to xorriso(1), genisoimage(1) or mkisofs(1)
           by specifying this option.

           For example:

            params='-JrT -V "My Disk Image"'

           would specify Joliet (-J), Rock Ridge (-r) and TRANS.TBL (-T) extensions, and specify
           the volume ID (-V) as "My Disk Image".

           Take care when quoting this parameter; nbdkit passes the resulting string through
           another layer of shell interpretation without any sanity checks for unquoted shell
           metacharacters.

       prog=mkisofs
           Choose which program to use to create the ISO content.  The default is xorriso(1),
           genisoimage(1) or mkisofs(1) and is picked when nbdkit is compiled.  You only need to
           use this parameter if you want to override it at run time.

ENVIRONMENT VARIABLES

       "PATH"
           xorriso(1), genisoimage(1), mkisofs(1) or whatever you supply to the optional "prog"
           parameter must be available on the $PATH.

       "TMPDIR"
           A temporary copy of the ISO is created in "TMPDIR".  If this environment variable is
           not set then /var/tmp is used instead.  There must be enough free space here to store
           the ISO, which might be quite large.

FILES

       $plugindir/nbdkit-iso-plugin.so
           The plugin.

           Use "nbdkit --dump-config" to find the location of $plugindir.

VERSION

       "nbdkit-iso-plugin" first appeared in nbdkit 1.8.
