I am using an 8G CF card. (I was using dd to duplicate the card with
different size cards I was advised not to).
So I wrote the script below which basically:
1) runs fdisk to setup the device
2) makes the ext3 file system and the swap
3) mounts my old image "/" filesystem and the new partition
4) tar and untar the directories
5) run grub on it
6) set label for "/"
After I run all the above I get:
EXT3-fs error ext3_find_entry reading directory #129586 offset 0
then a couple lines later it remounts the root file system read only.
What have I missed in successfully make the CF card based on the old image?
