Hi,

I’m creating SD Card images `.sdimg` and the partitions in `sumo` have clear naming as follows,

```shell
# sumo
ls /media/ux/
primary secondary data

```

Now, I switched to `zeus` and the partition names are no longer exist,

```shell
# zeus
ls /media/ux/
01be7a09-37e9-48fa-972d-5c5282992a6a 01be7a09-37e9-48fa-972d-5c5282992a6a1 data

```

I would like to add the names as before so,

1. Kindly update your `zeus` repo to create `sdimg` with partition names or
2. Instruct me to add partition names in my build.

Thanks in advance.

Hi @danie I don’t know why this change was made but it seems to be something fundamental to the underlying WIC support. @kacf is this something that can be done?

I don’t think this is intentional, and I cannot explain off the top of my head why it happens. If we look at the zeus branch, we can see that [the data label is there](https://github.com/mendersoftware/meta-mender/blob/zeus/meta-mender-core/classes/mender-dataimg.bbclass#L18). I suppose it’s possible a `--label` option is also necessary when the [wic entry is made](https://github.com/mendersoftware/meta-mender/blob/zeus/meta-mender-core/classes/mender-part-images.bbclass#L140), but I don’t think it has any effect when using the `rawcopy` plugin. This would need to be investigated.

I tried that and if failed with an error about mkdoslabel blah. So I guess the rawcopy option does not support it.

I’ve tried this patch (basically adding ` --fstype=ext4 --label primary`) in `zeus` branch and it add the volume labels. I’ve tested in `imx8mmevk` `core-image-base` build and it’s working without any known hiccups.

@kacf If you guys can test it more extensively, I’ll be more than happy in providing a helping hand.

Thanks.

Hey,

I too faced this issue earlier! I think you’ve added `--label primary`, if so try adding `--fstype=ext4` along with `--label primary`.

I hope it should do the trick.

Cheers!
