(resolved) blkid gets it info from where?
For the sake of anyone who may have been looking for an
answer to this besides myself, I'd like to report two things

1) removing and recreating /etc/ and /etc/
seems to have fixed things. The boot process is not
interrupted by fsck errors;

2) while researching something unrelated to this problem, I
came across something that leads me to believe that the
reason there are incorrect associations between an ext2
file system label and two raid drives is the design of the ext
file system. If I understood the article correctly, ext2
somehow associates a label with any devices the filesystem
is connected to. My guess would be that the LVM partition
containing the ext3 fs is located on raid stripes on the
drives that show up in

I could be wrong in point two, but things are back to working,
so I guess it doesn't really matter.
