Linux usermode is a new type of gPXE image that can be run directly on a Linux host as any other userspace application. See how to use it.

The main goal of the project is to allow new debugging possibilities and shorten the development cycle.

On the other hand it also allows users to easily test their configurations and get a feel of gPXE quickly.

It's not really better, but surely a bit different. In short, it brings gPXE one step closer to the developer. Some specific points:

• catches invalid memory accesses
• full gdb support as any other userspace application
• easy to profile
• starts faster

Being able to also test drivers in userspace is on the radar.
