Hi all,

I am trying to eject the cdrom from a livecd after certain stage...
Now assuming that it is possible to eject,please consider my issue!!!

The OS boots into a regular user by default...so i am unable to use the eject command to push out the drive...
However if i try pfexec eject it works....but then again it works only when the system is completely up and running not at some intermittent stage in the boot process.

How do i change the my id to a Superuser then execute the eject command ,then once the eject is done with, i would like to revert back to the ordinary user?
Secondly this code should be incorporated into one of the boot scripts,
So that after a certain stage during the boot, the drive automatically ejects......

How do i do it.....

PS:i urge you to consider that ejecting the media on a livecd is possible.

Thanks
