Guidline: avoid two ways of fiddling in config files (if possible)

[Thomas Güttler]

After thinking about it again, it is obvious, but I was blind first.

I had a formular which modified /etc/sudoers

But it I better practice to have a custom file in: /etc/sudoers.d/

Is there a saltstack guideline for new comers which could add this "secret knowledge"?

It all depends on how you want to maintain your files.

Some users use the module directories for different services, some modify the main config file.

I don't think it is SaltStack specific, it more depends on the user and the services.

Also on software version and distro: e.g. autofs in centos 7 will read
/etc/auto.master.d, in centos 6.current it presumably supports that but
is missing the required DLL. There's a open ticket in RedHat. In earlier
versions of autofs that wasn't even an option.

/etc/sudoers.d didn't exist a few years ago either.

Yes, but I think a general guideline can be found.

Yes, that's true. On my servers it is always available. But this can be different, if you
need to support old operating systems.

Currently the general guideline is the distro and software vendors move
towards .d/ setup if and where possible. As time permits. I don't know
of any general guideline for me as a user, except to look at a given
specific piece of software in detail.

Like I said, autofs is the same version on centos 6 and 7. The upstream
and centos 7 version support .d/, centos 6 build does not but has an
open ticket -- so hopefully it might support .d/ at some point. How do
you find a general guideline in that?

After thinking about this again, the guideline could be:

If possible, avoid modifying/editing files via configuration management. Prefer to write/put whole files

What do you think?

I am not a native speaker. I guess a better wording could be used.
