search for an exact match; if none found isolate an existing ip= kernel argument for removal.

How to configure Flatpak apps for PKCS#11 and smart cards

Flatpak allows users to manually configure filesystem paths that will get passed into the Flatpak application sandbox via flatpak override. This feature can also pass in a unix socket, which works to pass in a dynamically started p11-kit-server socket from the host to access PKCS#11 devices. This will let you access web sites requiring smart card certificate authentication from a web browser installed via Flatpak.

Pre-requisites

Flatpak installed and working
Web browser that supports p11-kit installed via Flatpak (ex: Microsoft Edge or Chromium from flathub)
systemd, pcscd, opensc, and p11-kit packages installed on the host
