It should be possible to use a label or device name for a mount in the image partition action

[martin-petzold]

Currently debos uses UUIDs for the /etc/fstab entries. However, in some cases when using an A/B system upgrade machanism this can lead to the problem that partitions can't be mounted on boot. See related issue for RAUC: rauc/rauc#1149

The image partition action should have an option to use either the label (LABEL=...) or the device name for the specific entry in the /etc/fstab.

completly agree; currently we workaround this by not autogenerating /etc/fstab then manually creating it e.g.

 - action: filesystem-deploy
   setup-fstab: false
  - action: run
    description: Create fstab
    command: echo "PARTLABEL=system	/	ext4	defaults,rw	0	0" > ${ROOTDIR}/etc/fstab

We could extend the filesystem-deploy action somewhat to add addtional properties. This could be something like fstab-mount-by: label with uuid as the default (current case).

But if "filesystem-deploy" is already executed, how can then the fstab file be created in ${ROOTDIR}?
Maybe you mean the other way round?

I would suggest to add the property to the image-partition action. The mountpoints are defined in image-partition and should be customized using other than UUID, e.g.

    mountpoints:
      - mountpoint: /
        partition: rootfs0
        identifier: [uuid|label|device]

Also it would be good, if mountpoints would support bind mounts.

@martin-petzold please open a separate issue for bind mount support.
