Probably be udev. Note that it's a directory.

dpkg -L udev | grep static

Nothing for that, so it's probably created by some udev function.

> /dev/.udev

Definitely udev.

> /dev/.initramfs
> /dev/.initramfs-tools

Probably udev.

Check the udev package for what files it needs.

rkhunter probably needs to know about these files and not report them.
Hopefully it'll still check them to make sure they're the files they're
supposed to be.

ciao,
