From 4893cc08acc81bfc2f8730ea108574aedae909aa Mon Sep 17 00:00:00 2001
From: Fernando Rodrigues <[e-mail]>
Date: Fri, 4 Jul 2025 20:09:06 +0000
Subject: [PATCH 2/2] xen/tools/hotplug/Linux: patch external binary calls

This patch replaces all instances of executable calls and static FHS
paths in the hotplug scripts with at-padded variables that can be
replaced by replaceVars during a Nix build.

Signed-off-by: Fernando Rodrigues <[e-mail]>
