Well, as I said, I later realized that I did not need to edit that much but that was only on editing my third script when I found out about using 'none'. I started off by using IMGFILE=/path/to/my/chroot/dir and leaving CHROOT alone. That required editing qmount to add a case for a directory which I later reverted.

However, valdur55's post did not cure the "Nothing to do" problem, I had to edit closechroot thus:

Basically, adding a test for $IMGFILE!=none in two places and removing -m in the call to fuser as it was causing aforementioned issues.

I have also edited qchroot to alter some mounts but that is just my preference and I am not suggesting that it should be in any way taken seriously. I just did not think ED needed to know about my entire /home tree (which would include ED recursively). Mounting user's home dir ought to be enough for everybody
