how about running MAKEDEV sda in a known directory, to
create the sda* nodes in /var/tmp for example?
only thing to watch out for is that /sbin/MAKEDEV has been modified to
go "if udev installed, cd /.dev".
which is a bit stupid if you ask me.
so if you do if -x /.dev mkdir /.dev; cd /.dev; /sbin/MAKEDEV sda
then check the major/minor nums on /.dev/sda* then you have no need to
rely on /dev/sda* existing or not existing.
