Ok, I'm confused. After I rebuilt Minix with Amoeba, I copied the new kernel from /usr/src/amoeba/kernel/ into /usr/src/kernel/...but ps doesn't work. It worked before I included amoeba... What's wrong?

Ps knows about the layout of some kernel structures. You must recompile ps if you changed kernel structures. You do not need to copy the Amoeba kernel into /usr/src/kernel since you could tell ps where it is and save the necessary data into /etc/psadatbase (ps -U) but you need different ps for normal and Amoeba kernel. -- -- Ralf Wenk -- ralf@ptavv.ka.sub.org

The ps(1) program is one of those nasty programs that need be recompiled after a change in the kernel/mm/fs proc table, _or_ after a change in the number of procs/tasks. Recompiling a kernel _with_ Amoeba enabled in- creases the number of tasks with 5, sooo: make f=ps !!
