Comment:
On further testing, it turns out `IFS=,:/` is not sufficient because it doesn't recognize whitespace as a separator. As a consequence, `$kver`, `$arch` and `$status` all contain leading spaces. That causes the test on line 35 to fail and modules are never removed when the package is removed.

Try, for example, with this version of `xbps-triggers` and `dkms` installed along with one or more kernels:
```sh
dkms status
xbps-install nvidia-dkms
dkms status
xbps-remove nvidia-dkms
dkms status
```

The output of `xbps-remove` will show `Removing nvidia-dkms-515.57_1... ` and regenerate your initramfs images, but it will not print any messages about removing the module for specific kernels. The final `dkms status` will report an error and provide an incomplete listing of installed modules because it chokes on `nvidia` after the package files are removed.
