Bug#701223: follow-up thoughts

[Alexander Perlis <aperlis@math.lsu.edu>]

It occurs to me that the BOGUS value in /target/dev/disk/by-uuid might 
be a spurious filesystem signature left over from a previous install? 
I've noticed that the partman ext2 formatting goes really fast compared 
to the ext3 and ext4 formatting, so presumably less data is being 
written, perhaps allowing old superblocks to survive. One might 
furthermore presume that the installer code doing population of 
/target/dev/disk/by-uuid/ is different from the code doing the 
population upon reboot, and one could then theorize that the installer 
version incorrectly pays attention to leftover superblocks that aren't 
really part of the ext2 partition. However, this theory doesn't explain 
how the graphical desktop task ends up fixing everything prior to reboot.
