how does kernel code call plan9 system calls, does it perform a
trap from kernel back into kernel space and make the request just
like a user process or is there a more direct, subtle route?

the short answer is that it doesn't. but
I'm kind of sleepy. But if I managed to read your mail correctly...
when the kernel wants to do something that can be done with a system
call (mostly read, write, open, ...), it uses the device tab directly, like in
devtab[c-type].write(chan, ),
using Chan instead of fds in this case.

Thanks to all who replied on-list and off it.
using namec and calling through the device tab looks like what I need,
calling sysopen() with an array of integers seemed just too crufty, I
