Title: Re: [Sisuite-users] using a loop mounted .img file as the client image

Ah I didn't know about not being able to put the file on the hard drive
that is the source.  I'm not intending to do that, but I had made an
image of a node system , was trying to test the image file while it was
still on the node.  That was not working, and now I know why.  Thanks!

I wonder if I can use a file system utility to shrink the image file
down to the size of just he data?
