With the symlink:

  lrwxrwxrwx 1 root root 41 Jun  2 06:31 /var/lib/pcsc/drivers -> /home/vagrant/.guix-profile/pcsc/drivers/

Then I tried to run:

  pcscd --debug --foreground
  00000000 pcscdaemon.c:347:main() pcscd set to foreground with debug send to stdout
  00000077 pcscdaemon.c:623:main() cannot create /var/run/pcscd: Permission denied

Running as root appears to have worked:

  sudo -E --debug --foreground pcscd

Then as a user, "gpg --card-status" works. Haven't tried any other
functionality yet, but that's a good start.

So this seems like a somewhat complicated workaround, and making a
proper pcscd service would reduce the complication significantly.  It
would obviously be slightly preferable to me for gnupg to support
smartcards out of the box. :)

live well,
