digitalmars.D.learn - Learning D as main systems programming language

I'm new in the programming, systems programming especially, but I 
want to learn D more as a systems programming language and by 
that I mean avoiding libraries at all. My goal is to write a 
simple operating system totaly in D (using Assembly wherever is 
needed) and by progressing in that project, learning this 
powerfull language as the main systems programming language. Any 
help/advice on this goal will be really helpful/appreciated. 
Thanks in advance.

Based upon what I've read on the forum:
Try and get a minimal druntime first. Doing so will make you 
understand what is required to make it work.
You won't have access to the GC so a lot of language features 
(like slices) are out of the question.

There are some copies of druntime floating about for embedded 
which will probably help you.

I don't know how easy it would be to get a bootloader to call a D 
kernel although it has been done.

Pretty easy if you use GRUB. You can just compile a regular linux 
program with a linker script and load it right up.

My minimal.zip (a bit of a misnomer as it is more than minimal 
including some experimentation) has some code to run D on bare 
x86 metal
arsdnet.net/dcode/minimal.zip

Slices are fine, it's just the slice concatenation operators that 
must be disabled. This is easily accomplished by simply not 
implementing the runtime functions that support them, thus 
causing a linker error if used.

Isn't it written in D1? Not sure about that...

So what if it is written in D1? :) It should not be a big problem 
to "port" it to D2.
Second interesting project that is kinda related to the topic: 
https://bitbucket.org/timosi/minlibd .
