Is it possible to boot Linux with user space applications from file/image on disk?
I can copy content of any live image (for example from http://www.debian.org/CD/live/) to separate partition with any FS supported by grub and boot from it.
But how about booting from file instead of partition?
During searching I found that users name this as "Poor Man's Install" but most of them use partitions instead of single file....
