|
What are profiles?
|
||
|
|
------------------
|
||
|
|
Profiles are different configurations for different scenarios.
|
||
|
|
This means you can use the 'home' profile to setup things
|
||
|
|
differently than at work, where you would use either
|
||
|
|
no profile (standard configuration) or the 'work' profile.
|
||
|
|
|
||
|
|
|
||
|
|
How to use profiles?
|
||
|
|
---------------------
|
||
|
|
Simply pass 'cprofile:PROFILENAME' (like cprofile:home) to cinit.
|
||
|
|
|
||
|
|
|
||
|
|
How to pass argumenents to cinit?
|
||
|
|
---------------------------------
|
||
|
|
How to pass arguments to your init system depends on your operating
|
||
|
|
system and on your bootloader.
|
||
|
|
|
||
|
|
Linux
|
||
|
|
~~~~~
|
||
|
|
Under Linux the init-system gets the kernel arguments
|
||
|
|
(see linux.kernel.eats.arguments) as arguments.
|
||
|
|
So you can use
|
||
|
|
|
||
|
|
kernel /usr/src/linux/vmlinuz cprofile:work (grub1,grub2)
|
||
|
|
append="cprofile:work" (LILO,yaboot)
|
||
|
|
|
||
|
|
Other Unices should work like Linux, please consult your local
|
||
|
|
documentation.
|
||

|
||
|
|
How to configure profiles?
|
||
|
|
--------------------------
|
||
|
|
It's very simple: Normally cinit would call /etc/cinit/svc/init as
|
||
|
|
the first service (with all its dependencies). If you pass 'cprofile=wireless'
|
||
|
|
to it, cinit will start from /etc/cinit/svc/wireless
|
||
|
|
instead.
|
||
|
|
|
||
|
|
So the only thing you have to do is to create a service directory
|
||
|
|
below /etc/cinit/svc with the name of the profile you want to use.
|
||
|
|
|
||
|
|
You can simply copy the init-dir and use it as a template:
|
||
|
|
|
||
|
|
ei # cd /etc/cinit/svc; rsync -a init yourprofile
|
||
|
|
|
||
|
|
Standard cp will copy the linked files, not the links, that's why I use rsync
|
||
|
|
You could also use tar:
|
||
|
|
|
||
|
|
ei # cd /etc/cinit/svc/init; tar c . | (mkdir ../myprof; cd ../myprof; tar x )
|
||
|
|
|
||
|
|
That's it!
|
||
|
|
|
||
|
|
|
||
|
|
