Can I run Ubuntu in a changeroot jail?

[John J. Boyer]

I am using Redhat Enterprise Linux, but I occasionally get questions 
about Ubuntu from people who want to use my liblouis and liblouisxml 
braille transcription software. I don't want to set up the machine for 
dual-boot. So I am wondering if I could run Ubuntu in a changeroot jail 
or something similar for occasional testing.

Thanks,
