I remember a while back, that someone wanted a quick way to 'hot' mount optical
disks.  Well I wrote a program to do this, but I just now remembered that some-
one else was interested.  It's quite self explanitory.  I can't remember where
the anonymous ftp site is, so could someone either tell me or put this there.

Thanks.

/*  Optical disk mounting program, by Brad Post, University of CA, Berkeley.
    Notes:
	Makes sure root owns this program, and chmod it 4755, this allows 
	anyone else to run it.
	In the system call where there are [ ], you should put the location
	of where you want the disk to be accessible, I made it
		/MyDisk/Homes/optical
	for convience.  
	Remember to make the dir where the disk is rwx to all.  Also if you
	haven't done so already, before running the program, do:
		newfs -v /dev/od0a omd-1-all
	Then run the program normally, use the -s command to get help.

#include <stdio.h>

main(argc, argv)
int argc;
char **argv;
{
	void help();
	int i;
	char **last = &argv[argc-1];


	while (++argv <= last && (*argv)[0] == '-')
	   for(i = 1; (*argv)[i] != '\0'; i++)
             switch((*argv)[i])
    	     {
		case 'e': system("/etc/umount /dev/od0a");
			  system("/etc/disk -e /dev/rod0a");
	      		  break;
	/*  Remember to put where the disk is mount on where the [] are 
	    and remember to remove the [] :-) */
		case 'l': system("/etc/mount /dev/od0a [ ]");
	      		  break;
		 default: help();
			  break;
	      }
}

void help();
{
	printf("Usage:  optical -el \n");
	printf("  e = eject \n");
	printf("  l = load \n");
}
