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.
