I'm not necessarily against it, but this seems only related to yubikey
management in general (on Linux), rather than anything specific to Guix.
Of course, 'guix shell' is a handy way to do this, I just don't know if
this is needed in the cookbook. Then again, I guess the cookbook is a
way to build up associated knowledge for Guix, which won't be included
directly in the manual.

Otherwise, LGTM, but a user should be aware if they are using/needed OTP
before disabling it.
