Raptor Linux
*** Introduction ***
Raptor Linux is a mod of Ubuntu 6.06 (Dapper Drake)
This is unlikely to work on another version of Ubuntu, much less
another Linux distribution.
*** Features ***
* /sbin/init is replaced with Factor
* Virtual terminals managed by Factor
* Listeners run on virtual terminals
* Native support for static ip networking
* Crontab replacement
*** Install ***
# mkdir -v /etc/raptor
# cp -v /scratch/factor/extra/raptor/{config,cronjobs}.factor /etc/raptor
( scratchpad ) USE: raptor
( scratchpad ) reload-raptor-config
( scratchpad ) save
# mv -v /sbin/{init,init.orig}
# cp -v /scratch/factor/factor /sbin/init
# cp -v /scratch/factor/factor.image /sbin/init.image
*** Filesystems ***
# emacs /etc/raptor/config.factor
Edit the root-device and swap-devices variables.
*** Static IP networking ***
If you use a static IP in your network then Factor can take care of
networking.
# emacs /etc/raptor/config.factor
(change the settings accordingly)
The udev system has a hook to bring up ethernet interfaces when they
are detected. Let's remove this hook since we'll be bringing up the
interface. Actually, we'll move it, not delete it.
# mv -v /etc/udev/rules.d/85-ifupdown.rules /root
*** DHCP networking ***
If you're using dhcp then we'll fall back on what Ubuntu offers. In
your config.factor change the line :
start-networking
to
"loopback" start-service
"networking" start-service
Add these to your reboot-hook and shutdown-hook :
"loopback" stop-service
"networking" stop-service
*** Editing the hooks ***
The items in boot-hook correspond to the things in '/etc/rcS.d' and
'/etc/rc2.d'. Feel free to add and remove items from that hook. For
example, I removed the printer services. I also removed other things
that I didn't feel were necessary on my system.
Look for the line with the call to 'set-hostname' and edit it appropriately.
*** Grub ***
Edit your '/boot/grub/menu.lst'. Basically, copy and paste your
current good entry. My default entry is this:
title Ubuntu, kernel 2.6.15-28-686
root (hd0,0)
kernel /boot/vmlinuz-2.6.15-28-686 root=/dev/hda1 ro quiet splash
initrd /boot/initrd.img-2.6.15-28-686
savedefault
boot
I pasted a copy above it and edited it to look like this:
title Raptor, kernel 2.6.15-28-686
root (hd0,0)
kernel /boot/vmlinuz-2.6.15-28-686 root=/dev/hda1 ro quiet -run=ubuntu.dapper.boot
initrd /boot/initrd.img-2.6.15-28-686
savedefault
boot
* Note that I removed the 'splash' kernel option
* Note the '-run=ubuntu.dapper.boot' option. Unfortunately, this isn't
working yet...
*** Boot ***
Reboot or turn on your computer. Eventually, hopefully, you'll be at a
Factor prompt. Boot your system:
( scratchpad ) boot
You'll probably be prompted to select a vocab. Select 'raptor'.
*** Now what ***
The virtual consoles are allocated like so:
1 - Main listener console
2 - listener
3 - listener
4 - listener
5 - getty
6 - getty
So you're next step might be to alt-f5, login, and run startx.
*** Join the fun ***
Take a loot at what happens during run levels S and 2. Implement a
Factor version of something. Let me know about it.
