Subject: [PATCH 05/29] init: pass global variables into subs
Date: Fri, 15 Nov 2019 09:50:36 +0000 [thread overview]
Message-ID: <20191115095100.25633-6-e@80x24.org> (raw)
In-Reply-To: <20191115095100.25633-1-e@80x24.org>
Avoid 'Variable "%s" will not stay shared' warnings
when the contents of this script eval'ed into a sub.
We also need to rely on ->DESTROY instead of END{}
to unlink the lock file on sub exit.
