[lxc-devel] [PATCH] lxc-oracle: use db_load from container

[Dwight Engen]

This makes it so that the host doesn't need to have an old, compat
version of db43_load installed by using the db_load from the just
installed container. Some newer distributions do not even have an old
enough compat-db4 package available.
