Rumor has it that Justin Knierim may have mentioned these words:

10) Bug history:
Method 1: Unionfs used to oops the kernel. None of the official releases
were good enough without additional patches. We do use a patch which
seems to fix most of problems.
Method 2: both zisofs and "snapshot" device mapper target are in the
official kernel for a long time. dm-snapshot is well-tested by LVM users,
and actually is the resommended method of taking backups from a live system.
I haven't been on the LiveCD team that long, so I can only talk about what
I remember (I don't remember oops problems).
Modify the same file several times (usually 4-5 times for me) and the
unionfs filesystem can become b0rked, requiring a reboot.
The workaround for me always was to move the file[s] I needed to edit
(usually config/general.ent etc.) to a real drive and symlink them, or make
sure I only edit the file 2-3 times tops and reboot manually before unionfs
forced me to.
That's the way I understood it, anyway...
