Hi @malveo,

We have seen other reports of this e.g [/etc/fstab will sometimes filled with UUID-Entries (swap and boot) and will destroy upgrade/install](https://hub.mender.io/t/etc-fstab-will-sometimes-filled-with-uuid-entries-swap-and-boot-and-will-destroy-upgrade-install/2515/4).

Root cause is still unclear, as this is not something that is added by meta-mender.

But it is becoming a pattern, that might be worth investigating closer.
