Subject: [Buildroot] [PATCH] package/acpid: refactor init script
Message-ID: <20191023180512.21400-1-unixmania@gmail.com>

From: Carlos Santos <unixmania@gmail.com>

Adapt the format to the current template, used in other init scripts.

Move the one socond delay in restart to stop, giving acpid time to send
dying gasp to syslog.

Users willing to add start arguments can set the ACPID_ARGS variable in
/etc/default/acpid instead of rewriting the init script.
