PXE Boot TinyCore

[thockman]

Here is a script I created to build a PXE Boot image for tinycore. You can just add the tcz files in the base to build the image. I pulled together several items from other forums so thanks to them....

1) create bash script in temp folder
2) mkdir build dir in same folder and place tcz files and tinycore.tgz
3) modify script variables
4) run script ( don't forget chmod 700 scriptname)
5) the script will scp new tgz file to pxe location or you can copy later.
6) add tiny to existing pxe boot by copying bzimage to correct pxe folder where tinycore.tgz is copied.

Sample pxe boot
default 0
LABEL 0
kernel tiny/bzImage
append initrd=tiny/tc.gz

Also here is a synergyc service file to put in the base dir to autostart synergyc. You will have to modify to your needs...

Code: Select all

#!/bin/sh

case "${1}" in
	start)
		synergyc -n curly hostname or ip
		;;

	stop)
		pkill synergyc
		;;

	status)
		pidof -o %PPID synergyc
		;;

	*)
		exit 1
		;;
esac

And now the code

Code: Select all
