const KINIT_CMD: &str = "kinit -R -t '%{sasl.kerberos.keytab}' -k '%{sasl.kerberos.principal}' \
|| kinit -t '%{sasl.kerberos.keytab}' -k '%{sasl.kerberos.principal}'";Expand description
librdkafka’s default kinit command, overridden to single-quote the keytab and principal.
The default leaves them unquoted or double-quoted, so user-supplied values can inject shell
commands.
Default: https://github.com/confluentinc/librdkafka/blob/v2.10.0/src/rdkafka_conf.c#L950-L960
