Save variables to system

echo "export NODENAME=$NODENAME" >> $HOME/.bash_profile
if [ ! $WALLET ]; then
	echo "export WALLET=wallet" >> $HOME/.bash_profile
fi
echo "export LAMBDA_CHAIN_ID=lambda_92000-1" >> $HOME/.bash_profile
source $HOME/.bash_profile

Config pruning

pruning="custom" && \
pruning_keep_recent=100 && \
pruning_keep_every=0 && \
pruning_interval=10 && \
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.lambdavm/config/app.toml && \
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.lambdavm/config/app.toml && \

sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.lambdavm/config/app.toml

Set minimum gas price and timeout commit

sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.01ulamb\"/;" $HOME/.lambdavm/config/app.toml
sed -i -e "s/^timeout_commit *=.*/timeout_commit = \"2s\"/" $HOME/.lambdavm/config/config.toml

Create service

sudo tee /etc/systemd/system/lambdavm.service > /dev/null <<EOF
