Modified ISO

[Terry Chan]

Todd,

Here are a short list of steps I use to test the Lunar ISO's using
UML.

To create a root_fs using the Lunar ISO and the mkrootfs script from UML:

1. Run mkrootfs script from UML.
2. Create 512MB empty ext3 fs.  See mkemptyfs.
3. mount -t ext3 /mnt/root root_fs -o loop
4. mount -t iso9660 /dev/cdrom /mnt/cdrom
5. cp -a /mnt/cdrom /mnt/root
6. Edit /mnt/root/etc/inittab, c1:12345:respawn:/sbin/agetty 38400 ttys/0
7. Comment out c2,c3,c4,c5,c6 in /mnt/root/etc/inittab
8. boot uml with uml mem=128M ubd0=root_fs ubd1=emptyfs.swap.512
9. login as root, remount / with mount / -o remount,rw
10. Set /etc/localtime symlink
11. Removd /isolinux directory
12. Create /etc/lunar.release for the /etc/issue files.
