I switched my OPNSense to LibreSSL, but I switched back to OpenSSL because I noticed very choppy internet after the switch to LibreSSL (I will investigate that problem later, no idea why that happened, but that is not why I'm writing this post).
I noticed that before the switch from OpenSSL to LibreSSL Firmware Flavour was on default, so OpenSSL is/was the default. When I wanted to switch back from LibreSSL to OpenSSL I set Firmware Flavour back to default, but noting happened after checking for updates. I had to switch to OpenSSL specifically. I tested some furher and noticed that the new default was indeed LibreSSL and not OpenSSL.
Is this supposed to happen, or is this a bug?
Bump.
The default is enforced by the currently installed core package dependency on either LibreSSL or OpenSSL.
If you do a flavour transition, however, the core package (e.g. "opnsense") is not immediately reinstalled by the FreeBSD package management tool.
You can do it manually, but it is just a quirk that has no operational relevancy.
Cheers,
