Hi all.... I've got 3 kernels on my system, "A B C". I want to start different programs running according to which kernel I boot. What I whould like to happen is in boot.local (or where-ever) it say "if kernal A run X, if kernel B run Y". Is there anyway to do this? BTW I'm running SuSE 7.1......

You could grep on the output of uname -a uname -a Linux caliban 2.4.4 #7 Fri Jun 8 15:26:26 CEST 2001 i686 unknown for example: if echo `uname -a` |grep "#7" >/dev/null then\ run X elif echo `uname a` |grep "#8" >/dev/null then\ run Y else run Z fi (hope there are no syntax errors in here) But this is kinda ugly. If you rcompile a kernel, the number changes and you have to change the script. There might be a better way. hth,

use 'uname -v' and not 'uname -a' . it will return 2.2.19 or 2.4.5 or whatever. a lot easier to parse. For example, in my rc.local: if [ "`uname -v|cut -d\. -f2`" -gt 2 ] # do 2.4.x stuff else # do 2.2.x stuff fi - -- Douglas J.

What if all the kernels are 2.4.4 just different?? Don't know if thats the case but if it is then the first suggestion might work but again the # would change after any rebuild of it. There are extra version stuff in the TOP makefile of the kernel you could then use that to differenciate between the kernels. Just a thought because I've had to do something simalar. -- Mark Hounschell dmarkh@cfl.rr.com
