Deprecate the /usr/bin/hostid call by reading the /etc/hostid file directly. Add the spl_hostid_path parameter to override the default /etc/hostid path. Rename the set_hostid() function to hostid_exec() to better reflect actual behavior and complement the new hostid_read() function. Use HW_INVALID_HOSTID as the spl_hostid sentinel value because zero seems to be a valid gethostid() result on Linux.
The Solaris Porting Layer (SPL) is a Linux kernel module which provides many of the Solaris kernel APIs. This shim layer makes it possible to run Solaris kernel code in the Linux kernel with relatively minimal modification. This can be particularly useful when you want to track upstream Solaris development closely and don’t want the overhead of maintaining a large patch which converts Solaris primitives to Linux primitives.
To build packages for your distribution:
$ ./configure
$ make pkg
Full documentation for building, configuring, and using the SPL can be found at: http://zfsonlinux.org
