1. YubiKey is still not released by Fedora after boot when the YubiKey is inserted at the
time of boot up with the result that `gpg --card-status` fails (a problem from Fedora
Silverblue 39). `systemctl restart pcscd' is still needed to get `gpg --card-status`
to recognise the YubiKey. Windows does not do this.
2. `~/.gnupg/scdaemon.conf` setup by user in Fedora 39 seems to be gone in Fedora 40?
Pinentry errors in Kleopatra are emitted in Fedora 40 even when `gpg --card-status` is
fine, requiring re-creation of the `scdaemon.conf` file with the entry 'reader-port
Yubico Yubi` and a reboot (after which Kleopatra is back to normal). see

Fedora 40 beta is very impressive overall!
