Subject: [PATCH 4/5] guix-install.sh: Fix detection of SysV init system.
Date: Sun, 20 Dec 2020 18:28:38 +0100

Checking the presence of a regular file & not symlink (/etc/init.d/cron)
is not sufficient.

Detect a sysvinit system by running `/sbin/init --version' and checking the
output contains the string "SysV".

* etc/guix-install.sh (chk_init_sys): fix sysvinit system detection.
