Question

I have a rootfs boot image that I want to test by mounting on my local file system. How can I do this ?

EDIT: The file was a rootfs.img but it turned out I did not have the correct filesystem support in my custom kernel. pjz’s answer works once the fs support is there.

Need more info – what kind of image is it?

is it a file that’s a filesystem? if so you mount it like:

  mount -o loop rootfs.img /mnt/rootfs 

if it’s a subdir of your filesystem that you’r exporting via nfs, you can simulat ethe environment you’ve created by chrooting to it:

  chroot /path/to/nfs/rootdir/
