4.8.1 -> 4.8.2 Upgrade fails

[Keno]

Existing installation found!
creating backup of existing configuration
rmdir: '/tmp/tmp.vXru01/etc/systemd': No such file or directory
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
The operation has completed successfully.
Error: Partition(s) 3 on /dev/sda have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use.  As a result, the old partition(s) will remain in use.  You should reboot now before making further changes.
Failure: Unable to install image: http://repo.bisdn.de/pub/onie/accton-as4610/onie-bisdn-accton-as4610-v4.8.2.bin

It does work the second time, but of course this is problematic for unattended upgrade.

Hmm, it worked ok on my other switch. Not sure what the difference is.

Indeed, a weird bug. Not sure if we have seen it in internal testing so far. Will try to investigate and check if I see anything obvious (maybe a sync needed somewhere).
