It includes several new options for adjusting the image filesystem size as well as home.img and overlay file sizes. Expand the [[#editliveos.py --help]] listing below.
    
It includes editliveos.py, liveimage-mount, and temporary versions of fs.py, live.py, creator.py, util.py (pending incremental patches for livecd-tools acceptance).  The livecd-iso-to-disk version is not up-to-date with all the recent changes and improvements.

USAGE HELP  editliveos.py --help
 +
 +
              LiveOS_source must be entered as "live" to edit or clone the
 +
              currently running LiveOS image.  An attached LiveOS installed
 +
              device may be edited or cloned through its node id, such as
 +
              /dev/sdd1, or, if it is mounted, through its mount point path.
 +
              An .iso image file is addressed through its pathname, such as
 +
              /path/to/build.iso, or, if mounted, through the mount point
 +
              directory path.  A mounted Live CD-ROM image is addressed through
 +
              its device node, such as /dev/sr0.  Even a directory containing a
 +
              LiveOS and iso/syslinux folders with the appropriate files can be
 +
              edited or cloned through that parent directory path.
 +
 +
              The --clone option copies the home.img or persistent home folder
 +
              to the new build .iso file, allowing user customizations to be
 +
              replicated.  A new version of livecd-iso-to-disk with the
 +
              --copy-home installation option may be used to propagate clones.
 +
 +
              By default, other files and folders in the source device's outer
 +
              file system are included in the new build.  Options are provided
 +
              to --include, --exclude, and --seclude files or folders for the
 +
              new build.  The new builds are branded to distinguish them with
 +
              the --name, --builder, and --releasefile options.
 +
 +
              Space requirements for stageing the build files are estimated by
 +
              the script and compared to the space available in a -t <TMPDIR>
 +
              option.
 +
 +
              Invoke the --help option to learn about other optional features.
 +
             
 +
 +
Options:
 +
  -h, --help            show this help message and exit
 +
  -n NAME, --name=NAME  Name for the new LiveOS image (don't include .iso, it
 +
                        will be added.) Unless the name is prefixed with a
 +
                        colon, :, the build will be branded with a date-
 +
                        builder-Remix-releasename string, and the .iso will be
 +
                        named as NAME-arch-Ymd.HM
 +
  -o OUTPUT, --output=OUTPUT
 +
                        Specify directory location for the new .iso file.
 +
  -k KSCFG, --kickstart=KSCFG
 +
                        Path or URL to kickstart config file.
 +
  -S, --force-SELinux  Force setting SELinux attributes on install root.
 +
  -s SCRIPT, --script=SCRIPT
 +
                        Specify a script to run chrooted in the LiveOS
 +
                        filesystem hierarchy.
 +
  -N, --noshell        Specify no breaking to shell after edit.
 +
  -t TMPDIR, --tmpdir=TMPDIR
 +
                        Temporary directory to use for staging the build.
 +
                        (default: /var/tmp)
 +
  -y CACHEDIR, --yumcache=CACHEDIR
 +
                        Directory to use for for the yum cache. default: None
 +
                        (A temporary filesystem cache will be used.)
 +
  -e EXCLUDES, --exclude=EXCLUDES
 +
                        A string of filename patterns to exclude from the copy
 +
                        of the outer device filesystem.  See _copy_src_root().
 +
                        Denote multiple patterns as "pattern1, pattern2, ...".
 +
                        To exclude all device content except for the
 +
                        iso/syslinux and LiveOS directories, enter  "all".
 +
  -i INCLUDES, --include=INCLUDES
 +
                        A string of file or directory paths to copy to the
 +
                        .iso file in _copy_src_root().  Denote multiple files
 +
                        as "path1, path2, ..."  (The paths are referenced
 +
                        relative to the source mount directory, either
 +
                        /mnt/live/ or /run/initramfs/live for the running
 +
                        LiveOS, or /TMPDIR/editliveos-<random>/<srcmnt>/ for
 +
                        an attached or .iso file.  So ../../../<mount
 +
                        point>/INCLUDE or ../../../../<mount point>/INCLUDE
 +
                        may be used, respectively, to include files from other
 +
                        branches of the active hierarchy.)
 +
  -u SECLUDES, --seclude=SECLUDES
 +
                        A string of file or directory paths in the LiveOS
 +
                        filesystem to seclude from the final build
 +
                        configuration.  The user directory may be denoted with
 +
                        ~/.  Denote multiple files as "path1, path2, ..."
 +
  -r RELEASEFILE, --releasefile=RELEASEFILE
 +
                        Specify release file/s for branding.  Denote multiple
 +
                        files as "path1, path2, ..."
 +
  -b BUILDER, --builder=BUILDER
 +
                        Specify the builder of a Remix.
 +
  --clone              Specify copying of the home.img filesystem or the
 +
                        /home folder contents to the new .iso file.
 +
  --expand-image-gb=EXPAND_IMAGE_SIZE
 +
                        Specifies a new size of NN GiB for the image (or
 +
                        changing the size by a difference of +NN GiB, if a +
 +
                        sign is prefixed).  This is useful when a larger image
 +
                        is needed for a script, or during package updates in
 +
                        the chroot shell.
 +
  --shift-home-mb=SHIFT_HOME_MB
 +
                        Specify copying of the /home folder contents into a
 +
                        home.img filesystem of size NN MiB, or changing the
 +
                        size of an existing home.img filesystem to NN MiB (or
 +
                        by a difference of +NN or -NN MiB, if a sign is
 +
                        prefixed).  If NN = 0 (or nets to <= 0), the home.img
 +
                        filesystem contents will be shifted to the the /home
 +
                        folder, which is normally compressed; however, it
 +
                        subsequently will not have access to the --encrypted-
 +
                        home installation option of livecd-iso-to-disk.  If
 +
                        the selected or calculated size is insufficient for
 +
                        the current home contents, the edit will be to a size
 +
                        10% larger than the current home size.
 +
  --adjust-overlay-mb=ADJUST_OVERLAY_MB
 +
                        Specifies a new size of NN MiB for the overlay (or
 +
                        changing the size by a difference of +NN or -NN MiB,
 +
                        if a sign is prefixed).  If NN = 0 (or nets to <= 0),
 +
                        no change will be made.
 +
  --refresh-only        Specify replacing the squashfs.img or ext3fs.img of
 +
                        the source LiveOS installation instance with such
 +
                        files from the new build, and resetting any overlay.
 +
                        No new .iso installation file will be produced.
 +
  --skip-refresh        Specify no refreshening of source filesystems.
 +
  -c COMPRESS_TYPE, --compress-type=COMPRESS_TYPE
 +
                        Specify the compression type for SquashFS. Will
 +
                        override the current compression or lack thereof.
 +
  --compress            Specify compression of the filesystem image,
 +
                        ext3fs.img. Used when overriding an uncompressed
 +
                        source.
 +
  --skip-compression    Specify building the .iso with an uncompressed
 +
                        ext3fs.img file system.
 +
  --refresh-uncompressed
 +
                        Specify refreshing the source with an uncompressed
 +
                        ext3fs.img
 +
  --skip-minimize      Specify no osmin.img minimal snapshot.
 +
  -a KERNELARGS, --extra-kernel-args=KERNELARGS
 +
                        Specify extra kernel arguments to include in the new
 +
                        .iso file boot configuration.  Multiple arguments
 +
                        should be specified in one string, i.e., --extra-
 +
                        kernel-args "arg1 arg2 ..."
 +
  --extra-space-mb=EXTRA_SPACE_MB
 +
                        Specify extra space in MiB to reserve for unexpected
 +
                        staging area needs.
 +
 +
  Debugging options:
 +
    These options control the output of logging information during image
 +
    creation
 +
 +
    -d, --debug        Output debugging information
 +
    -v, --verbose      Output verbose progress information
 +
