I saw that a Solaris 10 patch for supporting Flash archives on ZFS
came out about a week ago.
Correct. These are the patches:
sparc:
119534-15 : fixes to the /usr/sbin/flarcreate and /usr/sbin/flar command
124630-26: updates to the install software
x86:
119535-15 : fixes to the /usr/sbin/flarcreate and /usr/sbin/flar command
124631-27: updates to the install software

I received the following message about the patches for zfs flash archive
support:
The submitted patch has been received as release ready by raid.central and
will be officially released to the Enterprise Services patch databases within
24 - 48 hours (except on weekends or holidays) or submitter will be further
notified of any issues that prevent SunService from releasing it.
Contact patch-mana...@sun.com if there are any further questions.
The patches are:
sparc:
119534-15 : fixes to the /usr/sbin/flarcreate and /usr/sbin/flar command
124630-26: updates to the install software
x86:
119535-15 : fixes to the /usr/sbin/flarcreate and /usr/sbin/flar command
124631-27: updates to the install software
A couple weeks ago, I sent out a mail about the content of these patches
and about how they should be applied. I have included that message
again, below.

-------------------------------------------------------
I have two pieces of information to convey with this mail. The first is
a summary
of how flash archives work with zfs as a result of this patch. During
the discussions
of what should be implemented, there was some disagreement about what was
needed. I want to summarize what finally got implemented, just so there
is no
confusion. Second, I want to bring everyone up to date on the state of
the patch
for zfs flash archive support.
Overview of ZFS Flash Archive Functionality
---------------------------------------------------------
With this new functionality, it is possible to
- generate flash archives that can be used to install systems to boot off
of ZFS root pools
- perform Jumpstart initial installations of entire systems using these
zfs-type flash archives
- the flash archive backs up an entire root pool, not individual
boot environments. Individual datasets within the pool can be
excluded using a new -D option to flarcreate and flar.
Here are the limitations:
- Jumpstart installations only. No interactive install support for
flash archive installs of zfs-rooted systems. No installation of
individual boot environments using Live Upgrade.
- Full initial install only. No differential flash installs.
- No hybrid ufs/zfs archives. Existing (ufs-type) flash archives
can still only be used to install ufs roots. The new zfs-type
flash archive can only be used to install zfs-rooted systems.
- Although the entire root pool (minus any explicitly excluded
datasets) is archived and installed, only the BE booted at
the time of the flarcreate will be usable after the flash archive
is installed. (except for pools archived with the -R <rootdir>
option,which can be used to archive a root pool other than the
one currently booted).
- The options to flarcreate and flar to include and exclude
individual files in a flash archive is not support with zfs-type
flash archives. Only entire datasets may be excluded from a
zfs flar.
- The new pool created by the flash archive install will have the
same name as the pool that was used to generate the flash archive.
Status of the ZFS Flash Archive Patches
---------------------------------------------------
I have received test versions of the patches for zfs flash archive
support (CR 6690473).
Those patches are:
sparc:
119534-15 : fixes to the /usr/sbin/flarcreate and /usr/sbin/flar command
124630-26: updates to the install software
x86:
119535-15 : fixes to the /usr/sbin/flarcreate and /usr/sbin/flar command
124631-27: updates to the install software
The patches are applied as follows:
The flarcreate/flar patch (119534-15/119535-15) must be applied to the
system
where the flash archive is generated.
The install software patch (124630-26/124631-27) must be applied to the
install medium (probably a netinstall image), since that is where the
install
software resides. A system being installed with a flash archive image will
have to be booted from a patched image so that the install software can
recognize the zfs-type flash archive and handle it correctly.
I verified these patches on both sparc and x86 platforms, and as applied to
both Update 6 and Update 7 systems and images. On Update 6, it is also
necessary to apply the kernel update (KU) patch to the netinstall image
in order for the install to work. The KU patch is
sparc: 139555-07 (or later)
x86: 139556-07 (or later)
It is not necessary to apply the KU patch to the system being archived.
