great... looks like that worked.
Now the last bit (copy this in as one full block):
cat >> /etc/config/fstab << EOF
config 'mount'
option target /
option device /dev/sda1
option fstype ext4
option options rw,sync
option enabled 1
option enabled_fsck 0
EOF
hit return, then
reboot
when it comes back, what is the output of:
df -h
