Hi there,
we are currently using RAUC in A + B mode with rootFS and appFS in each slot. So far so good, integration worked and RAUC does its job in updating all the slots and communicating with barebox. Now we wondered what is best practice in mounting the right appFS for the corresponding rootFS? When rootFS0 boots the appFS0 has to be mounted and when rootFS1 boots we need appFS1. We couldn't find a hint how to do that properly in the RAUC documentation.
Any help appreciated!
Regards,
Patrick

this can be done using proper udev rules for creating device aliases (symlinks)
that are then used for mounting.
How this is to be solved in detail depends a little on which storage type you
are actually using and how you boot.
Maybe you can add some more details here.
We have a work-in-progress Pull-Request targeting a documentation update for
this. It actually handles data partition mounting but the considerations are
valid for an appfs, too.
