commit 4bb63f7fb23b11591e2984ce87d4f36d80e29d65
Author: Michał Januszewski <spock@gentoo.org>
Date: Wed Mar 25 22:26:04 2009 +0100
gentoo: export the sysvinit RUNLEVEL variable for compatibility reasons
OpenRC 0.4.3+ no longer exports some sysvinit variables, including
RUNLEVEL. In order to avoid breaking themes and scripts which still
rely on this variable being present, we compute a suitable RUNLEVEL
value using the data available in OpenRC and then export it in
splash_call().
