- I'm running a public access UNIX system using Amiga UNIX 2.1. One
- thing that becomes very clear very quickly is that Amiga UNIX is not
- set up for multiple users. Running innd, nnmaster, and having three or
- four interactive users the machine stops pretty much dead in its
- tracks.
-
- I decided to tweak the configurable parameters in the kernel. I
- thought that decreasing the timeslice parameter might make the system
- more suited to interactive use. This is where the fun came in...
-
- I'm running gcc 2.3.2. Remaking the kernel with the appropriate
- changes was no problem. However this looked a little wierd to me:
-
- zikzak ~> dir /unix /usr/sys/unix
- -rw-r--r-- 5 root root 1486064 Dec 20 16:54 /unix
- -rw-r--r-- 2 root root 1487536 Dec 20 18:05 /usr/sys/unix
-
- I installed a modified kernel and rebooted. Guru. Some time later I
- had managed to restore the original kernel and all was well again...
- My question is this - what should I be doing to make the kernel that
- I'm not doing?
-
- Also, if anyone has hints on tuning an Amiga UNIX system for multiple
- users I'd appreciate it.
