NAME

       ltsp-update-image - Generate an NBD image from an LTSP chroot

SYNOPSIS

       ltsp-update-image [OPTION] [CHROOT...]

DESCRIPTION

       ltsp-update-image  generates  a compressed squashfs image from an LTSP chroot and exports it with nbd-server(1).  CHROOT can be a full path
       or a subdirectory of the /opt/ltsp base directory, and it defaults to the host architecture if unset.

	      The LTSP base directory. Defaults to "/opt/ltsp".

       -c --cleanup
	      Temporarily remove user accounts, logs, caches etc from the chroot before exporting the image. The chroot arch  is  required  to	be

	      configuration files already exist.
