This information will be used to determine which layout driver,
if any, to use for subsequent IO on this filesystem. Each driver
is assigned an integer id, with 0 reserved to indicate no driver.
The server can in theory return multiple ids. However, our current
client implementation only notes the first entry and ignores the
rest.
