Super frustrating. I'm sure I'm making it more difficult

I tried following 4.2.2.1

It seems like things should be easier. 9bootfat, 9pc, ini and 9front.iso. I think the frustrating part was being stuck dealing with a
usb device. I don't care about thumb drives. All of this should
be accomplished with an iso or 9front.bin or something similar. 

I ended up doing a dd from /dev/SDUxxx -of cd.iso 

But it was exactly 32G image. I have a limitation because its on 
AWS with an EBS of 32G maximum. 

In theory I should have been mount the ISO and dump the data, then
modify ini. But how in the world do you write the mbr you can't do 
that to a directory

disk/mbr -r mbr /dev/sdUxxx

So really I'm not sure how iso's are created in 9front. I suspect
some sort of rockridge format and a generic bootloader.

Here is what I ended up doing. I fired up qemu locally and performed
the install. Then I logged in and changed the ini file and added
console=0. Then I copied the 9front.img to the AWS ec2 instance. 
Everything came up fine text mode. Nice! and thak you for the help.

Honestly I would like to use the ec2 bare metal. Its already a 
hypervisor. I just don't know what to do to make that happen. I 
suspect I would need to dump the data into another EBS then force
the EC2 to load it. But i'm also not sure of the files required
beyond digging into inst/start and looking at the rc scripts. 

Or a docker would be nice. I saw a docker out there but it was two 
years old. It also ran on alpine linux, so someone manged to copy 
some files over. Maybe I don't want docker. Bare metal is better any thoughts would be much appreciated.
