Building and running Hurd in a subhurd/chroot?

[Svante Signell <svante.signell@gmail.com>]

Hi,

I want to build and install Hurd in an isolated environment, and from
there also try to build packages/run programs. Doing that a few
questions pop up:

- Run in a subhurd or chroot, which is best?
- I've found partial descriptions on how to do that:
  Is there somewhere a complete description of either?
  If I fail/get stuck will somebody try to help me or am I on my own?
  If somebody is willing to help, how: email, IRC etc?
- How to best do debugging in such an environment?

Thanks in advance.
