ltsp-update-kernels - copy LTSP chroot kernels to TFTP directories


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


Copies the boot/ directory from LTSP chroots to the TFTP directories in order to make them available to PXE clients. Copying kernels from inside NBD images is also supported. CHROOT can be a fullpath or a subdirectory of the base directory, and if it's unset, all avail‐ able chroots are processed.


-b, --base[=PATH] The LTSP base directory. Defaults to /opt/ltsp if unspecified. -h, --help Displays the ltsp-update-kernels help message. --version Output version information and exit.


Part of the ltsp package and the latest versions are available in source form from


/etc/ltsp/<tool>.conf: Upon execution the tool will read a configuration file to override built-in defaults. Values are NAME="VALUE" pairs, with # representing commented lines. most commandline options have an equivalent. an example Debian based system with an alternate base loca‐ tion, architecture, and distribution: # set alternate default location for ltsp chroot (--base) BASE="/srv/ltsp" # build an amd64 chroot by default (--arch) ARCH="amd64" # build a Debian sid environment (--dist) DIST="sid" /etc/ltsp/ltsp-server.conf: Each LTSP server tool will read a generic configuration file. This file is typically used for setting BASE, TFTP_DIRS and TFTP_BOOT_DIR. These settings are overwritten by those set in specific tool configs.
