It seems that if you boot F8T3 Live on a system that has an LVM PV within
a RAID1 array, F8T3 Live detects the LVM volume group without detecting
the RAID1 array that contains it.
This means that any changes to the volume group will cause the RAID array
to become corrupt, or so that the LVM physical volume will no longer be
detected properly when booting from the array.
I discovered this the hard way by using the F8T3 Live CD to make changes
to an LVM inside such an array so that I could install F8T3 on the same
array. (I renamed the LVs and changed /etc/fstab in one of them.)
Fortunately, anything important on the machine was already backed up.
This may be urgent because the F8T3 Live CD detected and used the swap
partition inside the LVM group inside the RAID1 array, which could cause
