[Libguestfs] Bind mounts

The test program below demonstrates how to use bind mounts to mount a subdirectory over the root directory. It is using the debug backdoor, but I guess we could consider adding a bind-mount API instead. [Note that guestfs_mount_options doesn't work because it expects the third argument to be a device, not a directory name.] Rich. ---------------------------------------------------------------------- guestfish -N fs -m /dev/sda1 <<EOF mkdir /root touch /root/test # Use -o rbind if there are submounts. debug sh "mount -o bind /sysroot/root /sysroot" ls / # The above command prints "test" as expected. # Check that umount-all still works. umount-all debug sh "grep /sysroot /proc/mounts ||:" EOF -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-df lists disk usage of guests without needing to install any software inside the virtual machine.
