Often the remedy for a problem is to boot from a CD, fix the issue and then boot from disk again. Alternatively, boot from an alternate boot environment and continue from there.
ZFS versions break the latter option. If you've updated to the latest ZFS you may not be able to boot an older version. Worse, there appears to be no bootable CD for SPARC any more. Even without updating the ZFS version, bugs in the older version may corrupt the newer version. For example, snv122 will no longer boot if you boot to snv103 from a different disk and then reboot to the disk with snv122 on it (it goes into a reboot loop). The only solution currently seems to be to always keep a copy of a bootable version of the current OS on a spare disk, something that may not always work and is prone to error. Is there any plan to make a live CD for SPARC, or does someone have a suggestion for a way to solve this problem some other way (i.e., other than making a bootable disk and keeping it on a shelf somewhere)?
