Re: REQUEST: Official Debian AmigaOne support

(I'm CC'ing you on this first mail; for any follow-ups I'll assume you are 
subscribed to the list.)

No, the debian-powerpc list should also be a porter list and be able to 
help with porting issues, but in general you can just not force people to 
care about your pet project: if nobody replies that could just mean that 
nobody was interested enough in the issue...

As long as you realize that you (AmigaOne community, not necessarily you 
personally) will have to do most of the actual work and research 
yourself, you are very welcome to do so.

The first step is the kernel. Without official support in the current 
Debian kernel packages there is no point in even starting on inclusion in 
the installer. For help with the kernel you should contact the 
debian-kernel list, or possibly the debian-powerpc list.
Note that for Debian kernel support any patches to the kernel source code 
will need to be pushed upstream into official kernel releases. The kernel 
team does not accept major patches just for Debian.
You also say that "support for A1 firmware" needs to be included. 
Inclusion of firmware itself is in general an extremely difficult subject 
because of licencing and sourcecode issues; it's not completely clear 
what you mean by "support" though.
There is also the issue that the powerpc kernel already has a lot of 
different flavors and there may be some resistance to adding another one 
if that should be needed.

General information on building the installer is available in:
It is also possible to build installer images using a custom kernel. Basic 
instructions for that are at:
