Are you going to add support for module state scripts? I tried passing the -s and --script commands and it says unsupported option. Also curious about permissions. Will I need to run a state script to set the permissions on all the overlaid files? Might be handy to have the permissions and owners set from the current files permissions when the artifact is generated. The single-file generator already seems to handle the state scripts and permissions…

It would make sense to make these improvements similar to what is supported by the `single-file` generator.

Though I have no plans on making any updates as my priorities are else where. I created this as a reference and would happily take contributions to improve it.

I modified it to work like the single-file generator to allow passing in other arguments such as state scripts. Not sure how to contribute though, I can’t upload the file. Should I just post the code?

Hi guys,

I tried the directory overlay update exactly similar to [this](https://hub.mender.io/t/directory-overlay/529). But I get these situations. It seems something related to compatibility I guess. I am using Balena Fin with the Raspberry Pi 3 Computing module.

Thanks in advance.

Your artifact is set to be compatible with ‘my-device-type’ but your actual device type is ‘raspberrypi3’. I think you missed a customization step in setting the variables for the artifact creation.

Thanks. I had forgotton to change my device\_type.

Now, I am getting this error after deployment. Here is the log.

It seems that for some reason you do not have a UID shell variable set but I thought that was a standard shell feature.

What distro are you running? What is your default /bin/sh?

I am using Raspbian on my device.

/bin/sh ? Can you give some more info on that ? I am quite new on using linux.

Thanks.

It looks like there is a bug in the dir-overlay script.

If you can add:

`[-n "${UID}"] || UID=$(id -u)`

into the file `/usr/share/mender/modules/v3/dir-overlay` just before the line that reads:

`case "$STATE" in`

then you will probably get past this. I’ll submit that as a proper bugfix for future releases.

How are you generating the artifact you are installing? Can you include a complete shell log showing the commands you enter and the output they generate?

When I set my DEST\_DIR to “/”, the deployment succeeds. I am not sure why I fail on /home/pi/dir\_overlay even though I have set the permission to 755 on both locations.

After the deployment succeeds, I am confused about what sort of output I should expect. After having used directory update and single-file update, I was expecting the overlaying directory to be located on the DEST\_DIR, with its subdirectories. I can’t find rootfs\_overlay directory anywhere on my device. Instead, I see backup.tar, manifest, and manifest.prev files at location /var/lib/mender/dir-overlay-install. When I extract the tar file, I could find the overlaying directories. Is it the way how dir-overlay works or am I missing out something?

Regards,  
Saman

The files in `/var/lib/mender/dir-overlay-install` are state files and backups which is how the update module is able to handle rollback.

I don’t believe you will see a directory named `rootfs_overlay/` but the contents from that directory should appear directly in your `DEST_DIR`.
