Almost all of it! It's a one-user workstation, which was essentialy idle. |

I read the man page of xz, but it suggested nothing to me. |

Done that. It extracts now, so 3) is the correct hypothesis, and "insane" is |
| 31 |
really the appropriate word. Of course, the hash digests are now wrong, so |
| 32 |
emerge still fails. Any idea how to find which amount of memory is needed? I |
| 33 |
would setup appropriate swap, if possible. The LFS site |
| 34 |
http://www.linuxfromscratch.org/lfs/view/development/chapter03/packages.html |
| 35 |
shows that there exists a tar.bz2 tarball. I think the ebuild should pull |
| 36 |
that... Can't believe there are no gentooers out there with boxes with less ram. |
