  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.

  I've by habit compiled all the tools statically for a long while
  now.

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

  correct.  but only me and my girlfriend can log into it, so
  security-wise it doesn't really matter.  although I do miss certain
  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.  :)
