different profiles on boot

[iphitus]

With this laptop I run all sorts of different configurations depending where I am.

 

The irritating thing is i have to login and run scripts manually.

 

eg: At school i have to manually run a script i made to start wireless.

 

I cant put this in init because the keyboard locks up or the kernel oopses when i set the WEP key.

 

I would like it to come up, just before I start X with a menu

 

- Home Configuration

 

- School Config

 

- Home 2 (no X)

 

And each of these runs a shell script. (third is optional)

 

I tried writing a python script to do this, but it's output never makes the screen and if i leave it it locks up init.

 

Are there any programs that i can use that will do this?

 

Aru? Do you know of any cool shell scripts that will do this?

 

I am running Arch linux -- but if you find anything, let me know.

This may be not exactly what you're after, but... http://muthanna.com/quickswitch. (Credit to anon).

[iphitus]

ok, thanks!

 

Quickswitch wont work because i have a shell script i need to run to get wireless working and it doesnt offer a chance to do that.

 

shortly after i posted that, i found something

 

It lets me pass an option to the kernel, eg: profilename=home

 

And i can call it from a shell script within linux and it will put that option into a environment variable with export (still listening? lol)

 

So im hacking a bash script to do what i want, wish me luck :D

Iphitus: Can you post what you found for the benefit of others?

You can change profiles from console as root with

# /sbin/set-netprofile "profile"

You might try this in your script.

 

In regard to passing an option to a kernel... If so, you can create two/more kernel stanza in the lilo.conf with different profilename=profile... My impression however is that you want change profiles right before X starts...

Thats what i am doing.

 

Ill post it when I finish it, although it will only really be useful for arch users

Ok, here it is,

Don't try and use this script on another distro -- It will ONLY work on arch.

 

You can use the attatched program, cmdinfo to pass stuff to the kernel and then include it in scripts and stuff using ' export profilename=`/sbin/cmdinfo profilename` ' replacing profilename with whatever you passed to the kernel.

 

Have fun

Arch... what exactly do you mean (sorry for the naive question). Can I use it on a MDK9.2, kerenl 2.4, laptop?

[iphitus]

Arch is a distro

Archlinux.org

 

You can use that program and include it in your own scripts, just not the script i wrote as it is arch specific
