net/kea: [2.6.3_1]: Unable to open database: invalid path specified - only /var/db as folder allowed

After a recent update of net/kea (now at 2.6.3_1), kea rejects to startup because we have our
lease database not within /var/db/kea, but in /pool/data/kea.

According to the documentation provided at

https://kea.readthedocs.io/en/latest/arm/dhcp4-srv.html#dhcpv4-server-configuration

this is a intended behaviour since kea 2.7.9. For me, this change in 2.6.3 came out of the
blue and hit hard.

To solve the problem for those having other folders in mind than the at compile time fixed
one, one has to set the environment variable KEA_DHCP_DATA_DIR before startup of kea.

I have no clear idea were to put the proper definition of this environmental variable BEFORE
kea starts up. I tried using /etc/login.conf:

[...]
:setenv=BLOCKSIZE=K,KEA_DHCP_DATA_DIR=/pool/data/kea/:\
[...]

but the downside is that the rc-script in /usr/local/etc/rc.d/kea requirs 

REQUIRE: LOGIN ...

before being effective. Consequence: net/kea doesn't start properly when KEA_DHCP_DATA_DIR is
set via /etc/login.conf.

I guess the approach regarding /etc/login.conf is as wrong as changing the rc.d script's
milestone from NETWORK to LOGIN.

Is there a clean way - apart from changing rc.d-script - to provide environment variables at
boottime?

Thanks in advance,

oh
