Warning about moving vars to the PKI

[TinCanTech]

If you see this warning about your vars file:

IMPORTANT:
  The preferred location for 'vars' is within the PKI folder.
  To silence this message move your 'vars' file to your PKI
  or declare your 'vars' file with option: --vars=<FILE>

Ignore this message, it will be removed in the next release.

Edit:

• Due to changes made in Improve vars auto load #1025, it is now safe to keep your vars file in your PKI directory. This is now recommended.

Please, do NOT put your vars file into your PKI.

The problem is due to setting EASYRSA or EASYRSA_PKI in the vars file.

First, establish if your vars file is Global or Local:

Global:

• The vars file is NOT in the PKI.
• EASYRSA and EASYRSA_PKI MUST NOT be set in the vars file. Otherwise, you have locked your vars file to a single PKI, which means it is not global.

Local:

• The vars file is in the PKI.
• EASYRSA and EASYRSA_PKI MUST NOT be set in the vars file. These settings are not compatible with a vars file in the PKI.

## Do NOT move your vars file to your PKI.

Note:
Setting EASYRSA and EASYRSA_PKI in the vars file is NOT recommended.
However, if you do set these variables in vars then it is still supported.

EasyRSA vars file is expected to be in the parent of the PKI.

Changing that in version 3.1.x has proven to be too intrusive.

Note:
EasyRSA has not made any changes to force vars in the PKI,
it has only added a warning to encourage that use.
That warning will be disabled for v3.1.7+.
