# Handles Linux kernel module loading.
#
# Module loading is implemented both for SysV and systemd based systems, to
# ensure this module is managed in either case.
#
# It also remains to be tested whether _both_ /etc/modules and /etc/modules-load.d
# are processed by recent systemd-based Debian systems; or if there are
# inconsistencies between the implementation and the documentation:
#
#   https://wiki.debian.org/Modules#Automatic_loading_of_modules
#
# Anyway, having this configuration in both places does not seem to hurt (much).

# In the future, this definition can also manage /etc/modprobe.d/ entries.
