start the validator process (i.e. "exec solana-validator ..."). This is
important because without it, logrotate will end up killing the validator
every time the logs are rotated.

As mentioned earlier, be sure that if you use logrotate, any script you create
which starts the solana validator process uses "exec" to do so (example: "exec
solana-validator ..."); otherwise, when logrotate sends its signal to the
validator, the enclosing script will die and take the validator process with
it.
