It would seem to me that you need to fix all the arlalib_* functions
to take the cell as an argument.

That's easy. Patch appended.

Right. Got to move the arlalib to a real library.

I haven't been able to figure out how this should work so I weaseled
out and just did the mknod. Once you know what's necessary to get it
done automatically...

Yes, adding some way of specifying the system call to use to kafs is
on my todo-list.
As long as you're not using Transarc AFS you should of course use
105. I added some text about that in INSTALL.
