Openwrt inside a user mode linux. Why would we even want this many ask?
|
|
|
|
There are potentially a lot of reasons, one obvious one to me, it allows
|
|
folks to 'kick the tires' without actually flashing up any hardware. It's
|
|
also a great environment for porting over packages, you can get a package
|
|
fully functional in the uclibc root environment inside a uml without actually
|
|
disturbing your 'real router', and then rebuild for a specific target once
|
|
it's fully tested.
|
|
|
|
This is a first stab at a build that 'just works' and there will be more
|
|
cleanup to come. The simple directions are:-
|
|
|
|
Configure for uml target
|
|
Configure with an ext2 root file system
|
|
build it all
|
|
|
|
In your bin directory you will find a kernel and an ext2 root file system
|
|
when it's finished. Just run it like this:-
|
|
|
|
bin/openwrt-uml-2.6-vmlinux ubd0=bin/openwrt-uml-2.6-ext2.img
|
|
|
|
The uml will start, and bring up an xterm with the serial console in it. No
|
|
networking is configured, but, it's a starting point. The resulting file system
|
|
has just enough free space to start kicking the tires and playing in the world of
|
|
'embedded routers' along with all the resource restrictions that come with that
|
|
world.
|
|
|
|
To configure networking and more, refer to the user mode linux documentation online
