tested and resolved, we've added this change in our cli to fix this deprecate option in opnvpn :

[edit]
vyos@vyos-ser-win# set interfaces openvpn vtun10 server topology
Possible completions:
   subnet               Subnet topology (recommended) (default)
   point-to-point       Point-to-point topology
   net30                net30 topology (deprecated)

Does it work?

Time of task extended for testing.

Note that this is only a difference in formatting, not a change in error reporting; the formatting will be restored to the original behavior for consistency of parsing.

This was a result of changes to make error reporting more explicit in case of errors in config dependencies; I will realign with error reporting without vyos-configd.
