  sort of, just mask out ximian-packages and other stuff you can't
  make dependencies for.  otherwise it supposedly works well.  I have
  to admit to using red-carpet mostly myself.

  hm, haven't tried that.

  now.

  Gentoo's default kernel supports this, as well as XFS, out of the

  correct.  but only me and my girlfriend can log into it, so

  parts of 2.4.18 these days.  :)

  oh, and yes, the box runs 0.9.1_beta7.  which has worked flawlessly
  as long as I've kept _far_ away from known bugs.  :)
