OpenSolaris Boot Support For ZFS Root FS on x86 and SPARC

Derkjan de Haan writes "I am glad to see progress is being made on the the ability of OpenSolaris to boot from a ZFS filesystem: 'This putback provides the ability to boot the Solaris Operating System from a ZFS root file system on both x86 and SPARC platforms. Full ZFS boot and install support will be available in a subsequent build. Because of the phased putback, we recommend waiting for the full boot and install support rather than attempting to use the ZFS boot features separately.'"

Am I missing something?

This is an article about System V UNIX, and it's in the BSD category and tagged bsd. WTF?

Honk! Honk!

The OpenSolaris distribution can already install ZFS root and boot, based on the previous putback. This current putback makes it more robust, especially when it comes to finding the root device after having been swapped to a different port. What's still missing is multidisk pool and RAID-Z boot support.

Sort of a checkin in Sun terms.

ob disc: I work at sun

a 'putback' is just a formal way to submit your updated source code to a source code control system (what is called a 'gate').

and in fact, the matching command is (yes, you guessed it) 'bringover'. seriously, it is.

You're thinking of the original SunOS. Solaris is SVR4.

Never, it is CDDL, and Linus won't have that in his baby.

First, in spite of the section, this article has nothing to do with BSD - it is about Solaris, which is a System V derivative. FreeBSD also has ZFS support, but does not have more than very limited support for ZFS booting (and none in the stable release, I believe).

As to when Linux will get support for ZFS, it requires one of two things to happen. Either Linux developers need to do a clean-room reimplementation of ZFS, or they need to modify their license to one that isn't incompatible with many other Free Software licenses , including the CDDL.
