No, that bug was on a different hard drive and was due to bad blocks. That 
instance was converted from ext4, while this is a new mkfs. The steps necessary 
to reproduce the BUG are simple - mount -o ro /dev/Arkadios/Root $mountpoint.
I'm currently running from my initramfs, with that old system  mounted ro and 
bound to /usr (since that problem only occurred when writing to the disk, it 
makes a passable recovery environment).
