On a fresh amd64 stage3: # emerge -v1 net-analyzer/munin # emerge --config net-analyzer/munin … Generating public/private rsa key pair. … unknown key type ecdsa Ideally the munin config should catch the failure and fall back to just RSA keys. See #390937, #402441, and #488814 for more about openssh[-bindist] not supporting ECDSA keys.
Created attachment 366406 [details, diff] Untested patch for handling missing ECDSA functionality.
Thanks for the patch, I will take care of it.
The bindist USE flag has been gone for some time so this issues is now obsolete.
