Home partition not mounted after update

[alex88]

I've mentioned this in the irc channel because it was happening with my custom image and I gave a try using this layer on a brand new project as in https://www.konsulko.com/getting-started-with-rauc-on-raspberry-pi-2/ to understand if my custom image was the issue issue or also on the default one.

It seems that even in a default configuration, the /home extra partition isn't mounted after a rauc update.

Just to give a quick example:

• build image as usual
• flash image to rpi
• boot and see that /home is in /etc/fstab (probably generated by https://github.com/leon-anavi/meta-rauc-community/blob/master/meta-rauc-raspberrypi/wic/sdimage-dual-raspberrypi.wks.in), /boot is also duplicated because of wic appending to the custom fstab file which already contains the boot partition
• create bundle with bitbake update-bundle
• download and rauc install the bundle on the other partition
• reboot
• after reboot on the other slot /home isn't mounted and /etc/fstab only contains https://github.com/leon-anavi/meta-rauc-community/blob/master/meta-rauc-raspberrypi/recipes-core/base-files/files/fstab so only /boot is mounted

So I think the two viable solutions are to either:

• add /home to /etc/fstab manually
• figure out why the wic generated fstab doesn't apply to rauc bundle
• or?

@alex88 There is no need to figure out why the wic-generated fstab doesn' apply to rauc bundle as wic is not involved in the image that ends up in the bundle. wic uses the generated rootfs partition image and manipulates this when creating the disk image. The RAUC bundle of course uses the partition image only.

So the proper solution for this is to place the mount into /etc/fstab via manipulation of base-files.bb or, if you have systemd, make sure you have a mount unit set up for home.

Got it thank you!
