'dkms_autoinstall' is useful for DKMS kernel modules. Juju often upgrades

units to newer kernels before charm install, which won't be used until the
166
machine is rebooted. In these cases, some modules may not be compiled for
167
the newer kernel. Setting this argument to True will ensure these modules

are compiled for newer kernels.
