I have downloaded easy-rsa3 version to my OpenVPN server for testing.
I did so using wget on the v3.1.2/EasyRSA-3.1.2.tgz file below Releases at
GitHub.

When I read the vars.example file I see that most of what I had to do in the
vars file before is not really needed anymore. :-)

But there are a couple of things regarding certs I don't understand fully so
would like to get explained:

# In how many days should the root CA key expire?
#
#set_var EASYRSA_CA_EXPIRE      3650

Obviously based on earlier discussions here about looming expirations I would
like to do this to raise the time to 20 years:

set_var EASYRSA_CA_EXPIRE      7300

However, the following seems also to be involved with expirations but I don't
know for sure what to do...

Do I need to also set these to 7300 to get a 20 yesr "working time"?

# In how many days should certificates expire?
#
#set_var EASYRSA_CERT_EXPIRE    825

# How many days until the next CRL publish date?  Note that the CRL can still
# be parsed after this timeframe passes. It is only used for an expected next
# publication date.
#
#set_var EASYRSA_CRL_DAYS       180

Isn't the last one dealing with client cert revocations?

Does it imply some automatic renewal of the revocations such that one does not
have to build and copy a new crl file every now and then even if no new user
logins have to be revoked to keep the server operational at all?

In easy-rsa2 there was no way to update a crl file without also revoking an
additional user and the whole server locked up after a very short time of a
month or so.....

I had to disable crl handling for that very reason....
