I did successfully upgrade from an ALIX-board (i586) to an APU2-board (x64) with options backup/restore (works great!). However, on boot I observe these messages on serial console:
Setting hostname to *xxx*.localdomain... [ OK ] Setting up firewall iptables v1.8.5 (legacy): Invalid MAC address specified. Try `iptables -h' or 'iptables --help' for more information. iptables v1.8.5 (legacy): Invalid MAC address specified. NIT: Entering runlevel: 3ables --help' for more information.
Are there somewhere references to the old mac adresses left over (where to search?) or can these iptables messages savely be ignored? Device runs fine so far and does its job.
PS: Every 15 minutes I also see this message from Addon wio in /var/log/messages:
wio: This RRD was created on another architecture
How to get rid of this? I followed all hints in https://wiki.ipfire.org/installation/arch-change.
