/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 location, 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.
