ltsp-update-image(8) System Manager's Manual ltsp-update-image(8)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.
OPTIONS -b --base=
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
compatible with the server arch.
-e --exclude=
List of dirs/files to exclude from the image. This is in addition to /etc/ltsp/ltsp-update-image.excludes.
-f --config-nbd
Generate appropriate nbd-server configuration files. It's automatically set if NFS isn't used or if other LTSP generated nbd-server
configuration files already exist.
-h --help
The application help page.
-m --no-compress
Don't compress the generated image.
-n --no-backup
Don't backup chroot.img to chroot.img.old.
-r --revert
Swap chroot.img with chroot.img.old and update kernels.
