All the actions by the mysql_replication plugin can be done by connecting to the NULL database. There is no need to connect to the 'mysql' db, since there are permissions problems when connecting to remote hosts, e.g. when you want to query "SHOW MASTER STATUS" on a remote host.
module.exit_json() does not like when the "changed" variable contains a
match object:
TypeError: <_sre.SRE_Match object at 0x81e2ae58> is not JSON serializable
Running the module with the argument "upgrade=yes" invokes an upgrade of
all installed packages.
While here clean up some comments.
Functionality requested by @qbit.
* Do not use the fstab parameter on openbsd for mounting
OpenBSD's mount command doesn't allow selecting which fstab file to use.
So if we're operating on the live filesystem (mount or remount) return
an error if the user specified an fstab file.
Fixes#5591
* Fix the logic inversion (thanks to @landryb)
The `service` module starts services that are not running when
`action=restarted` or `action=reloaded`, which is especially convenient
for initial deployments because it eliminates an extraneous operation
for when the service starts for the first time. This commit adjusts the
behavior of the `systemd` module to match.
Sets the SSH option `IdentitiesOnly=yes` in the SSH wrapper when a
`key_file` is provided to the git module. This option ensures that
the provided key is used. Otherwise, the system's ssh-agent could
provide undesired identities when connecting.
From ssh_config(5):
> Specifies that ssh(1) should only use the authentication identity and
> certificate files explicitly configured in the ssh_config files or
> passed on the ssh(1) command-line, even if ssh-agent(1) or a
> PKCS11Provider offers more identities. The argument to this keyword
> must be “yes” or “no”. This option is intended for situations where
> ssh-agent offers many different identities. The default is “no”.
