// with modification:
// * In chkconfig configuration [default_runlevels start_priority stop_priority],
// runlevels to be started by default is modified which should be consistent
// with LSB init configuration below. And two priorities is also modified
// to be consistent with installing code in library.
// * "Required-Start" part of LSB init configuration is modified according to
// https://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/facilname.html
// for service dependency ordering, like what systemd provides.
// See https://linux.die.net/man/8/chkconfig for more details
