unable to find validator machine directory for the on-chain WASM module root

[ThomasBlock]

i run binaries without docker.
on v3.1 there is an undocumented change?

https://docs.arbitrum.io/run-arbitrum-node/run-full-node

apt-get install sysstat -y
is now neccessary, otherweise we see
ERROR[08-09|18:13:21.175] Failed to start iostat command err="exec: \"iostat\": executable file not found in $PATH"

How can i fix this? Do i need to create more folders etc?

[ThomasBlock]

okay is guess it has something to do with these new variables, but what do i have to set?

mkdir /root/wasm

--validation.wasm.allowed-wasm-module-roots /root/wasm --validation.wasm.root-path /root/wasm

ERROR[08-10|12:47:22.920] on-chain WASM module root did not match with any of the allowed WASM module roots

[ThomasBlock]

okay i created this manually and now it's booting..

mkdir /root/wasm/0x8b104a2e80ac6165dc58b9048de12f301d70b02a0ab51396c22b4b4b802a16a4

--validation.wasm.root-path /root/wasm

In my case, I set --validation.wasm.enable-wasmroots-check=false since I don't set --validation.* options.
