Well I think I have more problems.  MEPIS uses ext3 file system, but in 
previous attempts to configure grub, it said that root was ext2.  I don't 
know if that is a problem or not.  Because I don't yet understand 
optimization flags, I didn't consciously set any (I don't know how).  Last 
night I recompiled the kernel again and this morning when I went to configure 
grub it gave me this message after I typed root (hd0,3):

Error 21: selected disk does not exist.

This has happened before and previous times I would restart my chroot 
environment and mount everything again.  I noticed that none on dev/pts type 
devpts (rw,gid=4,mode=620) is mounted twice and none on dev/shm type tmpfs 
(rw) is mounted twice.  Also when I try the logout before rebooting into LFS 
for the first time, most of the mounts say busy - unable to umount (don't 
know the exact output but I'm hoping you all know what I mean)

I don't know how I hosed this thing up, but if anyone can provide me with a 
fix. I would appreciate it.  If no fix is available, can someone tell me how 
to rebuild starting from chapter 6 using the /tools that I already have 
created.  I'm hoping I didn't blow it in the earliest stages of this thing 
but if a complete restart is necessary then that is what I will have to do.  
Please let me know.

Thank you.
