It HAS happened to me, but I've read the messages and been able to recover. I'm sorry I wasn't listening on the sysadmin-discuss alias when you had your problem, as I would have gladly helped you with the issue. As stated earlier, the only thing that LU changes is the LU stuff and the menu.lst on the BE. The presence of ZFS means that there are/were cases when ZFS boot support came out where the automatically mounted datasets in the zfs pool got "confused" between BEs. This was/is pretty easy to fix. All I'm trying to say is, your original BE is NEVER changed to the point where it is not bootable. However, it is possible for you to get the boot archive in a state where it won't, but it is recoverable. I simply find the use of the word "unsafe" too harsh for the reality of what the issue is.
