24: The Solaris 10 10/08 release provides the ability to install and boot a ZFS root file system. You can use the initial installation option or the JumpStart feature to install a ZFS root file system. Or, you can use the Live Upgrade feature to migrate a UFS root file system to a ZFS root file system. ZFS support for swap and dump devices is also provided.

34: 6685292 - install should support booting from zfs
35: 
36: This putback provides the ability install the Solaris Operating System on a ZFS root file system for both x86 and SPARC platforms. The work includes enhancing the Solaris interactive text installer, Solaris Live Upgrade, and Jumpstart (profiled install) features.
37: 
38: The ZFS boot and install features are available in the Solaris Express Community Edition (SXCE), build 90 release.

55: [[PSARC/2006/370 ZFS Boot Support (Build 88)>>Community Group on.86-90]]
56: 
57: This putback provides the ability to boot the Solaris Operating System from a ZFS root file system on both x86 and SPARC platforms.
58: 
59: * 5008936 ZFS and/or zvol should support dumps
60: * 5070124 dumpadm -d /dev/... does not enforce block device requirement for savecore
61: * 6521468 ZFS Boot support for the SPARC platform
62: * 6574993 zfs_mountroot() may need to call clkset() to set the boot_time kstat
63: * 6633197 zvol should not permit newfs or createpool while it’s in use by swap or dump
64: * 6661127 zfs_name_valid() does not support ZFS_TYPE_POOL
65: 
66: === Additional Details
67: 
68: * 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.
69: * This is a flag day for Cap-Eye Install users and existing users of transitional ZFS root file systems. Matching user-land libraries, kernel, and grub are required.
70: * Systems that already have ZFS root file systems can be bfu’d with this release, but bfu does not convert the legacy mounts (of /, /var, and so on) to ZFS mounts. Backwards bfu to releases that don’t support ZFS boot is prohibited.
71: * At some point, you are advised to reinstall your systems to achieve the "standard" ZFS boot configuration, which uses ZFS mounts, not legacy mounts. However, the system continues to boot with legacy mounts (at least for now).
