# do an `lsblk` and note the name of the device you want to install this on, for example `/dev/nvme0n1`, or `/dev/sda`.
# the name of this one will be the part after `/dev/`, so in the first case name of it would be `nvme0n1`.
# create a file in the directory where this file is, and create an attribute list with that name under the `main` attribute.
# so in the first case, put `{ main = "nvme0n1" }` in it.
