System OpenSSL on debian 9?

[Varbin]

Certain new features are now available with OpenSSL 1.1.0 where the bundled LibreSSL is (compared to OpenSSL 1.1.0) now outdated. With dynamic linking, OpenSSL can be updated separately from h2o (so no rebuilt is required).
Would it be possible to have a special "systemssl"-build (for example with the package name h2o-openssl)?

I'd like to see this as well -- ECDSA support, etc.

Thanks for reporting this. When this repository was created, bundled LibreSSL was newer than a system one but as you mentioned, it has not been correct in some distribution releases today.

I'll re-research SSL libraries bundled with the software and distributions and consider compile options.

I forgot to mention that from the commit 5214a01, the package should use OpenSSL library provided by each distributions except Ubuntu 14.04 and Debian 8 which don't satisfy the minimal version of OpenSSL and fallback to bundled LibreSSL.
