I'd like something more positive than "hope it goes away"... :-)

This allows me to do my irregular "does anyone care about the kernel ABI / API 
definition?" song'n'dance.

Currently we use standard unix semantics - char devices, block devices, 
sockets, etc. However there is no definition for what that interface actually 
does. We have (most of ?) SUSv3, but there are a lot of other things we're 
doing. Some (many?) of the features aren't getting used because:
1. Not known by userspace programmers.
2. Non-standard semantics and no tutorial / example material.
3. Random changes to features and lack of versioning.

We also have serious problems with management of header files. "Use the 
headers that came with your glibc" misses ioctl() definitions, which are 
inherently kernel interfaces, not glibc interfaces.

I'll again offer to moderate a BoF, at LCA (http://www.linux.conf.au) in 
Perth. I don't have anything like the answers, so its only worth doing if 
someone with a clue is interested. LCA BoFs don't have much time or many 
slots, so if there's a decent amount of interest, it might be worth doing on 
the Tuesday (say for a couple of hours, in the vacant third mini-conf slot). 

Does anyone care?

Brad
