Re: [9fans] DigiLand DL701Q quad core tablet
well, kernel binaries are different for terminals and cpu servers, but these are built from the same source code. in reality the kernel is the same modulo some drivers and one variable ( e.g. no vga in cpu servers). -Steve On 19 Dec 2014, at 03:15, da Tyga cyberfo...@gmail.com wrote: Plan9 kernel is monolithic with the drivers required for a specific platform compiled in.

Re: [9fans] DigiLand DL701Q quad core tablet
in reality the kernel is the same modulo some drivers and one variable ( e.g. no vga in cpu servers). It's actually quite easy to make a single binary which can be configured at boot time to be either cpu or terminal, depending on a plan9.ini variable. IIRC it's a few lines of code in each of boot.c and main.c. However I can imagine a scenario in which this would be a security hole.
