cinit - Profiles ================ Nico Schottelius 0.1, for cinit 0.3, Initial Version from 2005-06-04 :Author Initials: NS cinit profiles described. 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! Some examples ------------- Here are some examples we found in #cLinux: -------------------------------------------------------------------------------- profile name what it does musibox only start mp3blaster terminal start only minicom, which opens the serial line net-terminal start a respawning shell script, which starts ssh to the selected host video start X+mplayer, which plays the dvd/cdrom wireless What to start when beeing in an unknown wlan home/work selected services (nfs, ip, ...) for home or work --------------------------------------------------------------------------------
