Re: 64bit startup

[Sergey Bugaev]

Hello,

with the following hacky patch, I no longer see any crashes,
debootstrap --second-stage runs all the way and leaves me with an
almost full Debian GNU/Hurd x86_64 system \o/

Well, debootstrap does output lots of errors like

dpkg: dependency problems prevent configuration of openssh-server:
 openssh-server depends on ucf; however:
  Package ucf is not installed.
 openssh-server depends on runit-helper (>= 2.14.0~); however:
  Package runit-helper is not installed.

but that's an issue with the selection of packages and not with the x86_64 Hurd.

Nano works, I can write text! The network stack kind of works; I can
'curl http://example.com' and get *almost* the whole output, but it
hangs towards the end there.

Sergey
