Could you also add a brief comment here, what this line does as you did in the pr description? Otherwise looks good to me.

yeah np, i'll add that when i've got my t450s back in a working state (i've had to order a replacement touchpad for unrelated reasons)

by the way, i'd like to be able to reuse this code without copy-paste for other devices that need it, but i don't know nix well enough to know do that (obviously the device path could be different) |

hi, sorry to say i won't be able to work on this pull request and help it to be merged as i would feel bad abandoning it afterwards. my touchpad and by extension trackpoint is Officially Not Working anymore and i've not been able to repair it. |
as i discussed in detail in this issue on nixpkgs, the t450s (and likely other models) have a problem where they do not create the sysfs attributes for the trackpoint device early enough in the boot process for udev to configure them. this pull request adds a (sadly device-specific) method for triggering udev to configure the device once the sysfs path appears.
