Subject: [bug#49056] [PATCH] services: pcscd: Fix daemon signal handling.

From: Brice Waegeneire <[email-masked]>
Date: Wed, 16 Jun 2021 08:38:18 +0200

"pcscd" wouldn't handle SIGTERM as it inherited ignoring this
signal (and others) from its parent shepherd.  The constructor
make-forkexec, restore signal handling.  Fixes
<https://issues.guix.gnu.org/45202>.

* gnu/services/security-token.scm (pcscd)[start]: Use
make-fork-exec-constructor to start "pcscd".

Depend on patch <https://issues.guix.gnu.org/48987>.
