Seems to me you are making some flawed assumptions here about how things are supposed to work... Please take a look at the sysconfig-hardware package. That is the tool intended to set up devices at boot on s390 based on info from /sys. Quite probably it will need some extentions to support FCP, but I think it should be relatively straightforward. If you figure out what/how, please send a patch (by opening a wishlist bug report against the sysconfig-hardware package with the problem description and patch)! Cheers, FJP
