You are using `thud` branch of meta-mender? Can you also share the configuration options in `local.conf`.

Also please note that `mender-partuuid` will not solve your problem, see my comment here,

> Makes sense now, that partuuid only applies to the mender\_root variable and not to the mender\_grub\_storage\_device. I can not think of an easy way to get around this, because GRUB is not able to scan/probe for a partuuid. But I know of one user who has solved a similar problem using the GRUB [search](https://www.gnu.org/software/grub/manual/grub/grub.html#search) command, which supports looking up filesystem image by label or fs-uuid. But this would require changes to the grub.cfg file + making sure that the partitions are labeled accordingly on each update.
