Rgd [AR-556] – Adding vnstat ( and ZFS support to MOTD )

[dolphs]

Just flashed rockpi-4a current buster image and it looks like I hit

"  Error: Unable to read database "/var/lib/vnstat/wg0": No such file or directory Merge "eth0+wg0" failed. ",

which can be shown here

Also have been checking vnstat to merge wg0 but did not succeed,

perhaps one can give me a hand please? TiA!

These are the adapters present:

looks like this helped in the end: " rockpi-4a:~:# vnstat -i wg0 --update "

Nice catch. I have mitigated this problem this way:
https://github.com/armbian/build/pull/2839/files

and remove combinations at the end since i didn't find a better way
https://github.com/armbian/build/pull/2848/files

 

Well, all this has to be done automagically ...
