Subject: [bug#78700] [PATCH] gnu: tlp: Fix scripts.
Date: Thu,  5 Jun 2025 11:42:14 -0400

tlp provides a number of executables.  Before this change the "tlp" and "tlp-stat"
executables worked fine but the "bluetooth", "nfc", "run-on-ac", "run-on-bat",
"wifi", and "wwan" executables would give strange warnings.

* gnu/packages/linux.scm (tlp): Fix scripts.
<phases> [wrap]: Use wrap-script instead of wrap-program to preserve shell
argument "$0".  Don't wrap symlinks.
<inputs>: Add guile-3.0 for wrap-script.  Remove bash used for now removed
wrap-program.
