Using a file in /etc would break if someone would downgrade from
baselayout2/openrc to baselayout1.
Why not teach /sbin/runscript it's own version? With something like this
we could also do stuff depending on a specific version of openrc:
- --- src/rc/runscript.c
+++ src/rc/runscript.c

setenv("EINFO_LOG", service, 1);

That one should be fine. It has a pure 32bit userland, no lib64 or
lib32, just plain lib as libdir.
