The current satellite config lock code relies on bash scripts and
gnu diff, it must be run as root and hence it typically requires
docker. The old version will be removed at a later date..
I tried for several hours to run directly against cmdSetup() in
cmd/satellite/main.go, to avoid the ctx.Compile() call. I had no
luck.
