Since lib.mdDoc is already defined as just id, this commit is a no-op as far as Nix (and the built manual) is concerned.

A set of virtual proxy device labels with backing physical device ids.
|
|
|
|
Physical devices should already exist in {file}`/dev/input/by-id/`.
|
|
Proxy devices will be automatically given a `uinput-` prefix.
|
|
|
|
See the [project page](https://github.com/aiberia/persistent-evdev#example-usage-with-libvirt)
|
|
for example configuration of virtual devices with libvirt
|
|
and remember to add `uinput-*` devices to the qemu
|
|
`cgroup_device_acl` list (see [](#opt-virtualisation.libvirtd.qemu.verbatimConfig)).
