I just wanted to say that I am very close in getting Micro Core booting in EC2. However, it abruptly stops booting with no error messages after setting the language to C. I'm simply uploading a loopback image of TCL into S3 and deploying it from there. Inside the loopback file I have /boot which contains core64.gz, vmlinuz64, and grub/menu.lst. It contains etc/fstab file, a opt/* directory with the backup files listed in .filetool.lst, a tce/ with all of the packages I want installed and proc/ directory. I'm using a PV-GRUB 1.03 hd0 partitionless Amazon kernel id which will boot my image, so my grub menu.lst looks like:
default 0
timeout 0

As you can see it just stops after setting the language with no error messages. I'm not sure why it would be stopping. Could this have anything to do with TCL not finding a filesystem?
