After Douglas Freed talked me off the devtmpfs ledge on
#gentoo-releng, my current suggested mount changes are:

  -t:
    proc
  --rbind:
    sys
    dev
    portdir    
    port_logdir
    port_tmpdir
    kerncache
    ccache
    icecream
  drop:
    devpts (now that we --rbind /dev)
    distdir (now that we --rbind portdir)
    packagedir (now that we --rbind portdir)

For distdir/packagedir, I'd be find if the source defaulted to None
(meaning “don't mount anything”) but could be configured to a path
(meaning “--rbind this after you've --rbind-mounted portdir”).

Cheers,
Trevor
