Hey @wener.. As I mentioned in the original post, there's a default-new-key-algo setting... Is it still not possible to use specify something like "rsa4096/cert,rsa4096/encr,rsa4096/sign,rsa4096/auth"?? Would love to see some progress on this. Glad to help test.

Does gpgconf --reload gpg-agent trigger that command? that's the ExecReload setting in the systemd service unit I'm looking at.

Thanks for this @gniibe. I have long been frustrated by trying to save the correct "stubs" to have my keyring point at two different smartcards. It was common and even advocated in my former community to place one's master key on a separate smartcard (certify capability), with a different one designated for daily usage.
