Subject: Undoing chroot?
Date: Fri, 26 Jan 2001 10:31:40 -0800 (PST)	[thread overview]
Message-ID: <20010126183140.17534.qmail@web112.yahoomail.com> (raw)

Hello,

I have a linux bootable CD which executes a custom
init.  The job of init is to figure out on which
device the CD is located.  After finding the CD, init
mounts the device and executes a CHROOT to set the
root directory to the CD.

After I'm done I'd like to umount the CD and then
eject it by sending an IOCTL eject command.  But since
I executed a CHROOT I can't umount the CD, umount
complains that the device is busy.

So how do you reverse a CHROOT?

BTW, I use an initrd image and init is a C program,
not a script.

Thanks
