# lncm/bitcoind comes with a bitcoind user generated, unfortunately in kubernetes we can't use that one as we have forced
# rootless, so we switch to the user root to make fix-permission work.
# the actual container will then be started with an random user id but known group=root

# bitcoin-cli looks for the .bitcoin directory in /.bitcoin, but it is actually in /data/.bitcoin so we create symbolic links to the right places
