## This configuration file modifies the behavior of
## DKMS (Dynamic Kernel Module Support) and is sourced
## in by DKMS every time it is run.

## Source Tree Location (default: /usr/src)
# source_tree="/usr/src"

## DKMS Tree Location (default: /var/lib/dkms)
# dkms_tree="/var/lib/dkms"

## Install Tree Location (default: /lib/modules)
# install_tree="/lib/modules"

## tmp Location (default: /tmp)
# tmp_location="/tmp"

## verbosity setting (verbose will be active if you set it to a non-null value)
# verbose=""

## symlink kernel modules (will be active if you set it to a non-null value)
## This creates symlinks from the install_tree into the dkms_tree instead of
## copying the modules. This preserves some space on the costs of being less
## safe.
# symlink_modules=""

## Automatic installation and upgrade for all installed kernels (if set to a
## non-null value)
# autoinstall_all_kernels=""

## Script to sign modules during build, script is called with kernel version
## and module name
# sign_tool="/etc/dkms/sign_helper.sh"

## DKMS feature request:
## add /etc/dkms/framework.conf.d configuration file drop-in folder
## https://github.com/dell/dkms/issues/116

## Lower parallel compilation jobs to 1 if less than 2 GB RAM to avoid freezing
## of virtual machines.
##
## This does not necessarily belong into security-misc, however likely
## security-misc will need to modify /etc/dkms/framework.conf in the future to
## enable kernel module signing. See below.
