I am working through my Buildroot + RAUC example project[1] and after
modifying the HDD partitioning I can no longer install updates to the
boot partition however updates to the rootfs partition still work.
My boot filesystem is using boot-mbr-switch and it seems to be getting
confused by the fact that I have extended partitions but no primary
partition #4. The partition layout is:
P1 = Boot loader (with space reserved for boot-mbr-switch)
P2 = Rescue partition
P3 = Extended partition
P4 = <unused>
E5 = Rootfs.0
E6 = Rootfs.1
E7 = Uploads (bulk data, unsafe across reboots)
E8 = Persistent data (fully journaled, safe)
When I attempt to update the bootfs, I get the following. The exact
same commands worked before I changed the partition layout (adding the
rescue & upload partitions, forcing the use of an extended partition table):
````

Any idea why rauc is complaining that an unused partition overlaps my
boot partition?
I'll probably just shuffle things around and move the persistent data
partition to P3 and let the extended partition table take P4, but this
seems like it's a bug.
