- Remove the incus.sysctl drop-in file. This setting file overlaps with lxd's
sysctl settings, and setting these sysctls on boot even if you aren't running
containers is suboptimal.
We could come up with a complicated scheme for loading the rules once Incus
starts, as suggested in bsc#1233410, but ultimately these settings are only
really useful for production servers with >100 containers, at which point
admins are expected to tune their servers anyway.
So we can just remove it.
