Separation of the partitions for read-only and read-write mode

General Discussions

Hi,
I would like to separate the partitions for read-only and read-write mode (Multi-Partitioning). This will reduce the risk of failure. For example ‘/var’, ‘/swap’, ‘/tmp’, ‘/etc/resolv.conf’, etc. can be in read-write mode and the rest of the partitions to be in read-only mode.
Is it possible this to be done with Mender and how?
Currently, I am interesting for Raspberry Pi 3B+ and Raspberry Pi 4, but this is in general for all embedded, industrial and critical solutions.

Mender operates on the following partitions,

  • boot (optional)
  • rootfsa (stateless - can be put in RO)
  • rootfsb (stateless - can be put in RO)
  • data (read-write for persistent data)

And anything you want to keep read-write in the rootfs parts you need to link to the data part
