Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASMlibrary
driver.  The followingquestions will determine whether the driver is
loaded on boot and what permissions it will have.  The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface []: grid
Default group to own the driver interface []: oinstall
