Where to set environment for boot processes
 
Hi,

Where is the right place to set some environments variables for boot processes (those started from /etc/rc.d/rc.[SM])? I think, /etc/profile is not suitable, since it only effects environments of login sessions).

Thanks in advance,

You can put them into corresponding init scripts or even in inittab itself. More important question - why do you need that, what are you trying to achieve ?

Because this is embedded system, most programs started from init. Some environments dedicated to these program, such as MY_APP_DATA_PATH, need to be set correctly.

well from all above description I assume you have a application and you want to set up a path variable for that before it executes after the systems boots up!! is this correct ? if not it is still not clear what you are trying to do, if you can explain a bit in brief your requirement we would help you better.

taking the first situation, you can write a simple script to set up the env. variable and place it inside /etc/profile.d/, your script will be called everytime at startup.

SAbih,

I think /etc/profile.d/* scripts will not be executed before /etc/rc.d/rc.M get executed, my application was started from rc.M. So, setting variables in /etc/profile.d/* does not help.

have you tried exporting the variables directly at the top of rc.M (or just before your application is started there)?
