Just to be clear about procedures -- and not to put down flash archives as a way of doing things -- ufsdump/restore has been used for a long time to recover systems. It may not "create" a bootable disk on its own, but standard procedure is to do a ufsrestore of the partitions, and then install boot blocks. You will either be booted from a Solaris CD or from a hard drive and recovering to another hard drive, and it is a one line command. No big deal.
I once had a script running off cron at 1am on a particular machine that copied the boot drive format to another drive, ufsdump/restored all the boot drive partitions to the other drive, installed boot blocks, and used sed to fix things like /etc/vfstab and move the clone script, so, if the first drive failed and the system rebooted, it would just boot off the second drive successfully (and not try to clone itself again until I got a new drive). In that particular configuration, the edit of the vfstab was because it was originally configured to boot off, say, c0t0 and if the second drive became the active boot drive it would be booting off, say, c0t1. I could swap the drive, but the idea was to be able to enable a quick remote or automatic restart.
